I don't provide link on my photos for several reasons:
1. Most of my photos are re-posts from tumblr's photo blogs and have no info with them. A link to the blog would be pointless.
2. I most often post in the "random picture" threads which are as the name implies random and about posting pictures. As I see it they are to be viewed and enjoyed for what they are and are not intended to be a teaching moment. If and when I post in a more specific thread or topic I'll post up the link.
3. When I post photos I've taken myself I'll tell you. Most of the time these will be on my flickr page and there is a link in my signature to the page.
4. I don't post a link just to piss George (kash22i) off.
