You're right about not posting something you might want to sell but the trick there is you have to post what you sell sometimes to show the exact quality the buyer may expect or to actually show the image to people who might buy it.Then there are the occassions when you post something you didn't intend to sell but someone writes to ask how much you want for it...many times they want exclusive rights to it which you can't offer if its embed on 50,000 websites.Thats what actually led me to Deviant Arts and to discover this as one of my members asked me to check an image because someone wrote inquiring how much she wanted for it...needless to say she was shocked as was I to find the embed code there. In truth,this may have been there for some time without my knowing because their site is rather slow and I never really got attached to it like rosity and others.But it appears many of their members were unaware of it and so I came here to make sure that people who may be members over there knew about it so they could either deactivate their gallerys or remove them if they don't want people to take their images...but I didn't want to say it that way because they do have a great site and the owners are trying to clean it up.
