I have noticed people have pictures in their signature, and when I go to edit my signature, I see no place to upload a photo to it, how do others do it?

Use external hosting like Imageshack
and then use the [img] tag

ex: [img]http://imageshack.us/link to image.jpg[/img]

In more simple words, you need to find the url of the photo you want to put and then go to the edit signature and write this
[img]url of your image[/img]

I got it, thanks
