Go to User CP (Control Panel).

You can edit the text that you want and upload sig pics at the the Edit Signature tab.

Very easy ... I think that you need to have the pic sized the way you want it prior to uploading it. I believe mine to be 60 pixels high by about 350 wide. Computer monitors render pics at 72 pixels per inch. Don't know what that is in centimeters ...
