How to find an avatar?

[NovemberRain]

Hello! I know this is an old thread, but I was wondering if any of the mods/admins or members could help me. I noticed that member avatars differ in size. Some are wider and shorter, and some are taller, and some are what I would say a mix of tall and wide. I know it depends on the picture a person chooses to use, but I've tried changing the size of mine and it still looks "scrunched."

Is this something that just happens and can't be avoided, or is there a way to fix it?

Thank you!
