WHATS *.GIF & *.JPG?
Most web space providers prefer you have your pictures in these formats theyre just to different types of picture files. So if your having problems with uploading a picture this is most likely the problem. Its easy to change the format of a picture file, you can either right click and rename to yadda.gif or yadda.jpg (or you can do a Save As in paint and amend the box underneath the picture name accordingly). But whats the difference?
GIFS (*.gif): are the only format to save transparencies in. If you want any part of your picture to be transparent, choose this file type.
JPEGS (*.jpg): wont hold transparencies, theyll give the transparent bit a white back ground, but they are better quality than GIFS, so if your pic doesnt need transparency save it in this format.
Now if you want a pic under your name, then that is called an avatar. I'll find a post about avatars to help you. To add an avatar under your name, you will need to go into your profile to add one.
