im trying to put a photo that i have in my computer as avatar but it says error at this time when i do..i guess the photo has to be saved as a certain size.

When you use a custom avatar I'm pretty sure the size requirement is 48x48. You can't just pick up a picture you have stored on your computer, though. It must be something you have posted on a website. I also found out the hard way that you can't pick up pictures from certain sites. I had tried putting my picture on my yahoo blog, but yahoo doesn't let you link from your pictures on there. So...I have another little free website that I have the picture on so I can use it here.
