Ok so I want to put a link in my signature to my gallery...how do I do that? Also how do I have a picture put in my signature so that everytime I post something people can see my truck? Thanks for all the help fellas and ladies!!

 

Click on User CP at top left, then 'edit signature'

Copy and paste any link to either an individual picture or your gallery.
BUT bear in mind that dependent on how often you post, people will soon get bored with seeing the same picture.
Perhaps change the pic at regular intervals or only post a full signature every 10 times you post.
But as I say it depends how often you post.
If it's only every couple of weeks or so it won't matter so much.
