-What is the rule regarding replacing existing pictures with better quality ones? Like is it allowed?

-If yes, what is the process for replacing those pictures? Do I just post the better quality pic in the comments, and then an admin will replace the original image?

-And not a question but would be nice to be able to see who deletes comments and be able to contact them by PM or something.


The reason for my questions is because I submitted a couple pictures a few days ago and some were deleted.
