I don't know what or where no follow is. I don't see that anywhere in my profile.You do need to check yes to always attach signature to posts.
I did my signature pic by going to.www.tinypic.com
. Click browse, choose your pic. Then under resize choose thumbnail and click upload. Enter anti-spam code. When the next screen pops up, copy the forum code and paste it into your signature box in your profile. Save profile and you should be good. If it comes out too small then repeat the process above but choose website/email in resize section.
to post a pic on a thread post then use steps above but pick message forum in the resize section and paste the code directly into your post.
