If you are using Lilypie, you need the second code, or the one that says:
[b]PseudoHTML, UBBCode™ or BBCode
Used on many message boards that don't allow HTML.
It gives you a big long code like this

You need to put into the Signature box of your forum details the [ i m g] everything in the middle &[/ i m g ] (like I have in red)
make sure you include the brackets and there are no spaces in your code..
