Limitations on Signatures.

Can we put any kind of Limitations on Signatures as there is no re-sizing agents.
For example I could post and image link that could take up a lot of space below.

Therefore it can become a problem with big images or text.

Anyway I was wondering is it possible to put any kind of limitations for signatures?

PhpBB3?

Add this to your CSS:

Code:

.signature_div img {
    max-width: 100px;
}
