Just make sure that the pictures you post are your own, or if they are not, they need to be copyright free/open source, and you just need to credit the original artist :)
As long as you are clear, people tend not to mind, I think it is just because you can earn money from posts on here, people flag things when they don't think they are yours.
More looking to help you not get flagged in future than wanting to accuse or anything :)
The picture you posted has his signature in the corner...?
