As a halfway measure, maybe RO could give vendors an easy way to promote an image that used their item. You can already click on the gallery link and see what other people are doing with a product (which is great, I use it), but maybe a way for a vendor to say "this image is great and really shows off my work", highlight it, and give the artist some kind of reward (e.g., could even just be points).

But personally at this point, I basically just assume I will want to rework the shaders on the majority of what I buy. It's just part of setting up a scene.
