Signature problem

Hi,
a member of my board has siggie problems.
She uses the [img] tag to implement a picture, but after a few days the pic stops being there and the siggie looks like this:

Code:

[img:a387]http://i15.photobucket.com/albums/a379/milliondollarsxybaby/hustlesig.jpg[/img:a387]

I even tried to put the siggie in myself but it kept occurring.
Other members don't have this problem. I think it's got something to do with these weird numbers that keep appearing in the tags.
What's wrong there?

I've seen that happen before on my site, but the problem was back when signature length was shorter, so I'm not sure why it would be happening now.

Try hosting the image at a different place (servimg, for example), and see if that works
