Possible sources for images:
- Magazines and newspapers
- Draw the image yourself
- If you must use the Internet, the Microsoft site has thousands of useful images on it (though it can sometimes be tricky to download from)
- Clipart is sometimes a good option, apart from anything else as the images are designed to be clear (need pictures of animals…? vegetables…?). Example, above.
- More clipart on Discovery.com…
- Another clipart site that that I can recommend
- Yahoo News, if you are looking for something topical (choose 'News Photos')…
- Google… and most of the other search engines, too (a9.com, Dogpile, Yahoo and Windows Live, for example) — don't just use Google!
Note the two items that I've put first on my list — and which (in)famous name I've put last. You want a good image — don't go to Google-is-Evil: it has zero interest in the quality of the images it steals, and how suitable they are for use in a language class certainly isn't one the criteria it uses.

I can recommend all of the following, with the Dudeney book and those published by OUP being particularly good for one-off lesson plans based on a particular website/page.
- The Internet and the Language Classroom, Dudeney, G. (Cambridge, 2000)
- Dave Sperling's Internet Guide, Sperling, D. (Prentice Hall, 1998)
- How to Use the Internet in ELT, Teeler, D. and Gray, P. (Longman, 2000)
- Internet and ELT: the impact of the Internet on ELT, Eastment, D. (Summertown Publishing, 1999)
- Internet English Gitsaki, C. and Taylor, R. (OUP, 2000)
- The Internet, Windeatt, S., Hardisty, D. and Eastment, D., (OUP, 2000)
- The Internet and Young Learners, Lewis, G. (OUP 2004)
- Teaching English with Information Technology, Gordon-Smith, D. and Baber, E. (Modern English Publishing, 2005)
Note that most of the above — all published fairly recently — make no mention of blogs, one of the big phenomena, the big success stories, of the Internet. Some don't even mention Google! What is published about the Internet quickly becomes dated (note particularly how the links the books give will quickly break).
Some publishers have companion websites for their "resource books" (also course books) — partly to combat this problem. The three OUP books above all do (registration required):
