How to put Images in Your Post
First, go to the image you found and Right click it.
Second, click Save As. Save it to My Pictures.
Third, go to an image hoster.
www.imageshack.us and
www.photobucket.com are good ones to use.
Fourth, Click Browse, and select your picture. Go to Upload.
Fifth, Copy and paste the BBCode for it. On ImageShack that is HotLink for Forums 1. On PhotoBucket, that is the image tag.
Sixth, Paste the Code in your UserCP under Edit Signature.
That should do it.
