Multimedia Exchange - Re-size pics of truck

I have gone to pbase.com to open a gallery, but the picture in my sig won't show up what am I doing wrong?

I was wondering the same thing I have pics to post but it says they are to large to attach. :bang:

Bump.

I see one picture in your sig, one broken.

We only allow one sig pic here, and the limit is 500x150 pixels. If you
could shrink that to make it fit, that would be appreciated.
