But, there are a few reasons. It occurred to me to list/discuss them after this past Wednesday's post, wherein many of you commenters said you did or did not.
1. Copyright. My pictures are mine. I might not be a good photographer, but I own that. And, watermark or not, pictures I produce are mine, and I don't want to just hand 'em out. You can look at them, that's what pictures are for. But use them? Represent them as yours? I'm pretty much not okay with that.
