List image filenames in Product Admin?

Hi..

Does anyone know how to tweak the code to list the image filenames instead of names, in product admin? This would be much better because then you don't have to give your images long names to help you identify them.

For example, on 2 seperate product pages i might have 'additional images' that share the same name. Obviously on those product pages i would just want to have a short caption like.. i.e, "Red & Cream", not "Product 1, Red & Cream". The former makes it hard to distinguish which image belongs to which product in the admin pages.. because the images are listed by their names and not their file names. Does that make sense?

This would be extremely useful.. hope someone can help. I think the files i need to edit are admin/product.tpl or product.php?

Thanks.
