I understand that flash and SEO are like chalk and cheese (don't go together) But say if you really want to have a small flash image on your home page amongst lots of juicy text can it really hurt?
Whats really bad is an entire flash page, because you have no text to index. You'll be fine. Not sure if the file size might affect G's indexing of the page though, G I think can index flash stuff now and I know they don't like hugh file size pages.
