I am adding some pages with quite a few images to a site.
I would like to know would it be a good idea to include in the imagename.jpg keywords/phrases relating to the subject of the page and image. I am thinking of the fact that search engines look at keyword density. Would the name of the image count to keyword density. I know I should be putting keywords/phrases in the alt tags of the image but should I put them in the name as well or should I stick to some short easy name?
I've found that giving images keywords is a bad thing as it helps people find them in an image search who may then "lift" them for their own site. Makes it easier to track them down though if they don't have enough brain cells to change the name of the image. Cryptic is better for image names in my book.
