Hi Paolo I think your best bet is to name the image file as accurately as you can, without intentionally trying to keyword stuff it. Name it something useful as if a person should get an idea of what the image is just by reading the name. And don't make it too long. I'm not a complete image SEO expert - but here's some resources you should check out first; http://www.seosmarty.com/image-seo/ http://www.seomoz.org/blog/image-seo-basics-whiteboard-friday Renaming every photo is not over-optimization if it makes it easier for the user. Like I said, just don't keyword stuff the name Hope this helps! -Dan
