Hi! I was looking through your tumblr and read the anon message, even though it was really annoying I think that something that is wrong is that you put your tumblr URL as the source and not the photographer's. I know you add a comment where you say who is the owner but if people click the photo they get redirected to your tumblr and not the photographer's website.
i just put the source because i’m the one who posted the picture. it links it to my blog if people want more posts that are similar. and it’s really easy to find photographer’s websites… just google search it. and i find that the only reason people want me to put the website is because they just want a place to go get some pictures to post on their own blog. if you ask me a photographer’s website in a message, i am willing to redirect you :) (also, a lot of the pics i post don’t come from photographer’s actual websites but just modeling agency portfolios)
