Embedded images, particularly inside Flash animations are particularly indiscernible by search engines trying to index your website.
Embed images in your web pages for graphical illustration only. Use text for any content which you would like search engines to pick up.
Some websites display content inside images, which search engines cannot read.

Always use an Alt text value to describe what is in the image, and make sure the file name of the image says something about the contents also.
