hello,
i was wondering because i read it on another forum, how true is it that if you post a picture of lets say a signed baseball card online, that someone can right click your picture and get the address and location of where the picture was taken or scanned? i ask, because it was a heavy debate on another site that someone put they posted their collection online and 2 weeks later someone broke into their house and stole his entire collection. so people were debating just how safe or wise it is to post your item/collection photos publicly on a site for all to see. is it safe to do? any worries or concerns about posting ones collection online? your thoughts on this please?
