So now that we're all on the same page, and what Amy really wanted to know was how to rename all of her image filenames to the names of the products (probably Product.SEName) do we believe it would be better for SEO purposes to do this? Currently our images are named after the Product.ProductID, making them easy to find and control on our servers. As does BFG 9000 at 3MSelect, and I presume a lot of others. Undoubtedly it would make a difference in Google image search, but is it enough of a difference?
To be able to do this you would need to write a program to read in the ProductID, Name and SETitle and loop through all products changing the image names in the icon, medium and large folders. Achievable if you know enough C#, or other languages.
