Signature Help

[n00bl3t]

So basically, I remember I found a mod or script that allowed it so when users used a really large image as their signature, it would automatically rescale the image to fit into the forum box and then if the image was too big in height, it would add a neat scroll on the side to fit it in.

I know I can simply make/edit the usergroups so they don't add images that are too big but that isn't really my problem. I don't mind the large images, I just don't want a signature image messing up the general forum layout and break outside the lines.

Anyone know the code I would use to 1) Rescale the image to fit <--- ---> 2) Add a scroll to the signature if the Height goes over a certain length (Example: 300)

Thanks.
