I'm no expert, but all the photos I post are from my iPhone, this and other forums doesn't change them at all....previously I was using photoshop but that's only problems and my photos were rarely coming out right, sideways ect...
My main issued on this forum and this forum only, I rarely can see the photos on my iPad when I click on them I see a black page....I then have to click on download to be able to see them....maybe one day that will be fix
