First you need to upload the image to a host like imgshack or photobucket. They will give you an IMG code and if they don’t copy the URL.

Now when you get to the boards on the top right hand side below the banner it says “user control panel” click that and once the page loads on the left hand side you should see in white lettering “edit profile” click that and then click “edit signature”. When the page loads a text box will appear just paste the IMG code there.

If you do not have a IMG code then click the IMG button and paste the URL hit preview to test it and then sav when you are happy.

Don’t forget the signature rules do apply.
