I'm just curious' all...

Why do y'all care if someone uses one of your pictures?

I really couldn't care less if someone else uses one of my pictures. Though if it is a competing item, then it might chafe my drawers a bit, but I really think the only time I would give a rat's a...a...arm, is if there was something unique in my picture (such as a sequential number as is present on some chips).

Personally, I like to use my own pictures so I don't run the risk of someone saying "what you sent is not the one that was in the picture", but it's not uncommon for many listings to use "stock" photos of items (dolls for example) and I see nothing wrong with that, as long as the "stealer"s listing says "this is not the actual item". in it.
