Zan, Pete, glad you found it useful.

In addition to what Zan said, if you include the Latin name in the title tag, then be sure to include it in the text on the page as well as in the image alt tags.

The search engine "spiders" or "robots" are just little software programs that crawl from page to page trying to find out what each page is about. They only really "read" text (although recently Google has started to read Flash movies to some extent), so the only way they can find out the content of an image is by the filename and the alt tag you have given the image.

If you have given an image on your page the filename 1234.jpg and also given it no alt tag, the search engines have no idea about what that image contains and cannot index it.
