"I know that tumblr and Facebook are like enemies or something, but I have a fanpage in fb and the other day I posted one of your edits, and as I included the source (your blog), someone quite rude told me "What happens in tumblr stays in tumblr, bitch", and, despite nobody should tell the other what one can post and what cannot, I must ask for your permission this time, because I loved that last manip and I'd like to share it there."
I don’t mind if you share my work as long as I am given credit and you post a link to my blog, and also a link to the exact post on my blog would be better. if you just post the picture, then people are more likely to save it from your page, then upload it on tumblr. I would rather have a direct link to the post, so that they can reblog it. Thank you for asking permission though, I appreciate it.
