Quoted Message: Would it be of any use if we knew who was using our images?
I have one image that was purchased and then edited which makes it unique. THAT image has been stolen by a number of other web sites. It would be nice to know who purchased because then I would know the rest stole the image.
I think the reason for not disclosing identities of buyers is that some contributors would try to contact those buyers direct - and buyers just want to buy images & get on with it, they don't want to discuss the images they've bought or be pestered to buy more!
Of course, that's not to say I wouldn't like to know the identities of those who buy my images ;-)
As most have mentioned at one time or another, it's always nice to know how your images are being used. Maybe just a friendly reminder to buyers each time they complete a project that the photographers like to see the end result of how their work was used.
