Having recently taken the plunge and upgraded from 1.9 to 2.6, I notice that if I try to post a long image in a forum post (say, height of 2200px), it gets squashed to a height of 1200px. Posting the same image as a label in a course works just fine and displays at the original length, so it seems to be limited to forum posts.
My search of documentation and forums hasn't returned any results, and I haven't hit on a combination of appearance settings that preserves the original image. Does anyone have any ideas on how to force the forum to leave our images alone and stop squashing them?
