Finding images on the Internet

Introduction

Images form an integral part of the Internet; they appear on just about every web page that you look at - with perhaps the exception of this page! There are probably going to be two reasons why you're looking for images on the Internet - either to include them in a web page that you're writing for yourself, in which case you'll be looking for icons, bullets, backgrounds and other assorted graphics, or you'll be looking for an image in order to answer a query that you've been asked about. This page should hopefully provide you with some help in finding both types.

The legal bit...

I'm not a lawyer, and nor do I play one on the Internet. However, please bear in mind that when someone creates an image (and text, of course), they own the copyright on that image. Unless it clearly states that the image is in the public domain, please exercise caution over what you do with any of the images that you download from the Internet, and seek permission before including them on any web pages that you produce, or include in any articles that you may be writing for example. Hopefully the page with the image(s) on should be quite clear in informing you as to what you can, and cannot do with the image. I think the golden rule is that unless you are certain that the image is in the public domain, ask before using it!

Types of images

There are essentially two different types of image that you'll find on the Internet, and they'll have the extention .gif or .jpg. There are a small number of other file types that are slowly becoming more popular, but I'd be prepared to say that 99% of all the images you find will be in one or other of these formats. Photographs are generally to be found as .jpg images, while icons and cartoon type pictures with lots of block colour will be found as .gif images. For the most part, you can ignore this, although it may be important if you want a specific type of image for use on a web page as an icon. You'll probably find it helpful to focus your search on .gif images in that case. Alternatively, if you're looking for photographs they will most likely be found as .jpg images. However, this is not a hard and fast rule, so while limiting to a particular file type may give you a smaller number of hits, you may be excluding other images that would work perfectly well for whatever your purposes happen to be.

Using standard search engines to find images

Most of the standard search engines will provide you with some basic methods of searching for images, and the following are some examples of how you can quickly find images.

AltaVista
There are two methods of finding images at Altavista; the first is to use the switch 'image:' to locate any images that have a specific name. Consequently, if you are searching for images of the ship the Titanic, you could run a search like this - image:titanic and that will return hits of web pages that include any images called 'titanic' on them. You could focus your search a little more closely by doing a search for image:titanic.jpg to try and retrieve mainly photographs.
The problem here of course is that there is no saying that an image called 'titanic' is going to be of the ship - it might be a still from the film, or indeed anything that the web author thinks deserves the name titanic. Consequently, you will probably want to use the image; switch in conjunction with some other search terms. In this example, I would probably try and narrow my search down to something more specific by doing a search on AltaVista such as:
image:titanic ship iceburg "maiden voyage"
which should go a long way to excluding references to other types of 'titanic'.

The second way of searching for images at AltaVista is to use their picture finder. This is a specialised search engine which looks for images on web pages, and is a reasonably useful search engine. At this point I would caution you to consider using the filtered version of this image finder - you might be amazed at the number of undesirable images that it is possible to unearth with even the most innocent of words! The interface is simple and straightforward to use, and you have the choice of looking for pictures or moving images for example. Once AltaVista has returned the hits to you, it's simply a case of paging through them until you find the one that is suitable for your purposes. You may want to try the option of finding images that are similar, but in my personal experience this does not work terribly well, though you might always be lucky, of course!

HotBot
HotBot allows the searcher to input the term that they are interested in and instead of searching for it in the text of web pages, it will look for web pages that contain images of that name. This can be done by simply clicking in the appropriate box. HotBot does appear to be particularly strong on images - a search for images of 'titanic' returned 17,558 with AltaVista, but a whopping 109,640 with HotBot. This simply emphasises the need to focus the search more closely using other keywords.

Lycos
Simply input the term that you are interested in and click on the Pictures box to limit your search to images, rather than text on web pages.

Yahoo!
In common with AltaVista, Yahoo! provides several ways of finding images. Perhaps the most straightforward way is to simply type in the term 'image' or 'graphics' into the search box. Running a search for 'images' lists 31 categories and 9045 individual sites, so it is probably best used to give yourself an overview of the images that are available in different subject areas such as "Government > U.S. Government > Military > Navy > Submarines > Images" for example. If you are particularly interested in obtaining graphics for web pages, Yahoo! is probably going to be the one single best source to use. Simply search for 'web page images' and you'll get several hits to places in the Yahoo! hierachy that will be of assistance.

Yahoo! also has an image search engine, but surprisingly, this is not apparent from their opening web page. The Image Surfer can be found at http://ipix.yahoo.com/ and currently has six different categories - Art, Entertainment, People, Recreation, Science and Vehicles. You can either search for a specific term, or you can simply browse through the list of categories, although this does rely very heavily on luck if you are to get good results!

Image specific search engines

Stopstock
This site gives access to 11 different commercial image providers, and their databases can be accessed through the Stopstock front end. Unfortunately, you cannot do a multi-search across all providers, but you have to search each in turn, which can be a little tiresome. However, the search engine does work quickly and effectively, so it could be much worse, I suppose!
After the search has been run you are presented with a list of images that match your search term, and these are kept deliberately low resolution. However, even having said that, the quality is quite acceptable for general viewing. The idea behind this is, of course, to encourage you to register with the image provider and purchase the particular image.

The Amazing Picture Machine
I'm not sure I'd go so far as to call it 'amazing' myself, but it is simple, quick and easy to use. I suspect that their database is on the small size, since my search for 'titanic' only came up with two images, but they were both on-topic. After the search has been run you are provided with a summary of the results, and you can then choose to click on one in order to view the image. This is a nice touch, since it speeds up the whole process and if your search yields a great many results it's a quick and easy way of browsing through them, without having to wait for all the images to load.

The Corbis Collection
Another AltaVista based offering, this time giving access to over 500,000 photographs, so you're almost bound to find what you're looking for. My search on 'titanic' produced 172 results, but only a small number of these were related to the ship. Quite strong on space images.

The Sunsite ImageFinder
This is a collection of individual image search engines which between them provide you with access to perhaps the biggest total collection of images on the Internet. There tends to be a bias towards America, such as images on Californian history, the American Memory and the Smithsonian, but it should also be noted that there are also large collections of Architectural images, 13,000 images from the Australian National Library and a link to the NASA images library server.

Webseek
Webseek styles itself as a content based image, video search and catalogue tool. The format is the familiar Yahoo! approach, and the coverage is reasonably comprehensive, with 16 major categories to search in. My 'titanic' search resulted in 239 hits, most of which were related to the ship. Recommended.

Demon Image libraries and graphical counters
Demon Internet Services are one of the largest ISP's in the UK and they have put together a small (4) list of image collections that are designed to make it easier to add images to web pages. Not restricted to Demon users however, so if you want images on your pages, it might be worth while taking a look and following the links.

Aphids
This is a personal collection of links to image libraries, as well as general information on images, image tools and references. Useful starting point.

Image newsgroups

There are a great many newsgroups that are dedicated to images. People post photographs and images of different types and these can be saved using your newsreader and used for whatever purpose you want. Be warned though, since a great many illegally copied images turn up in newsgroups, so you need to be extra careful before using them. The main hierarchy is alt.binaries.pictures.<something else>. Your newsreader can be used to track down the particular group that you're interested in, though be aware that if you are of faint heart you might be disturbed at some of the image newsgroups that you will see.

What to do when you've found an image

Once you've found an image that you want to keep put your mouse over the image and press the right mouse button. Choose the save image option, and save it to an appropriate place on your own computer/network. It's really that simple.

Finding sounds on the Internet

The good news is there are a lot of web pages on the Internet that contain sound files, but the bad news is that the vast majority are of movie/tv clips and I suspect that they are in breach of copyright. Consequently, the warning that I gave for images should be repeated for sound files - before you make use of sound files please do check to make sure that you're allowed to use them. Some sites are explicit about what you can/cannot do with sound files, particularly those of film studios and record labels. Many of the sound libraries that you'll find have collected files from a variety of places, and they may not have been so rigourous in obtaining permissions to include the sounds that they make available. Therefore, if in doubt, check first!

Search engines

An increasing number of search engines will now give you the option of searching for sounds/web pages that contain sounds. The Altavista Photo and Media Finder allows you to search for web pages that contain certain sounds. A good practice search to try is 'connery' and this should return pages that have sound files that are either of the actor Sean Connery, or are impressions of him.

Lycos and HotBot also have sound options that you can chose when doing a search - with Lycos, just click on the Sound and Pictures option, and with HotBot you can choose to include audio in the advanced options.

Websites

There are a lot of websites that are simply libraries of sound files. Some of those that I use are:

Newsgroups

There are four newsgroups that people will post sounds to. You can be virtually certain that each and every one of these does not have copyright clearance!

How do I play them?

Well, it depends entirely on the type of sound file, and if you have the appropriate plug-in utility available. The majority of files are going to be .wav or .mid files, and you can simply click on the link for the file and your browser will then open a small window on the page and collect the file for you. You can then play it using the Windows default audio player. It should do this automatically, but you can replay it or save it if you wish to.

You may sometimes find that there are other types of sound file, such as MP3 files. To save going into great detail here, you should almost always find that if a site makes use of files that you cannot automatically play it will include a link to a site where you can download an appropriate plug in utility. Go to the appropriate site, download and install the utility and you'll then have no problem listening to the file!
