Just got a phone call from someone informing me that one of my hummingbird photos graces the entrance to a another local web forum (taken without my permission, of course). That, I guess, is the downside of putting your work out so others can see it. Someone is always lazy or feels that they should be able to use your work as they see fit.
Probably would been happy to give them permission but they never bothered to ask. Where I come from, we call that being a thief.
