signature

can someone tell me the step by step way to put a signature?

1 find a picture you like
2 right click the picture and click properties
3 copy-paste the web that it gives you
4 then you come back here on the site and click profile then signature
5 your gonna see a small thing that say img or image (click that first , insert web site that was copied and re click image or img again)
6 go to preferences (still in profile) go down and look for always attach my signature and you click yes
