How to add a picture to User profile ?

Might be a silly question but how do you add a picture to your personal profile for this forum? Do you have to have a web site with the picture on or can you upload a picture to this forum ??

you can attatch a picture to your post and then link to that

How do you add a picture to your post ?

Then how do you find out what the address is of that ?

I will try to add a pic to this one

Got it,
cheers
