For some reason I am not able to attach an avatar to my profile. The avatar is within the parameters and shouldn't pose any problem. Any help with this would be greatly appreciated.

Nevermind, this thread can die because I figured out the problem

But the solution can be useful for someone else, post it !!

The solution to my problem was the correct parameters for the width and height of course. But I also had to exit out of the site and log back in and then it would allow me to put in an avatar. Hope this helps others who have a similar problem.
