The signatures of my users are not showing up as images but as http links. Is there anyway to get them to appear as images instead without them having to redo it manually?

Is the signature source :



or

www.example.com/me.jpg

[Rivers]

believe it's [img] but its now showing as www.example.com/me.jpg (http://www.example.com/me.jpg) in the imported forum

What is this set to :

AdminCP > vBulletin Options > User Profile Options > Allow [IMG] Code in Signatures
