So after making my account I've been trying to figure out how to change my profile picture to something different. I have tried as many different strategies as I can think of to get it to work. I tried smaller-sized images, I tried different file types, but nothing worked. where do I find the information that dictates what images are valid for use as a profile picture & what are not; is that information even listed anywhere? Because at this point, I have run out of ideas of where to look or what to try; this is pretty much my last resort.
