WC3 valid image resizing

[S@NL - BlackBik]

I'm looking for a image resizer that is WC3 valid.
I've downloaded almost every resizer that is available on vBulletin.org, but every single one of them uses the onload attribute in the image tag.
This gives the next WC3 validation error on all pages where it kicks in: "Error: there is no attribute "onload"".

Right now I'm using the highslide resizer from ry125. It works great, but I really would like to find one that has another approach and doesn't use the onload attribute in the <img> tag and therefor will be WC3 valid.

I've seen hints that this can be solved by using css style and the onload function in the body tag, in which this attribute is allowed. But it goes far beyond my pitiful programming skills to make this hint a working hack.

Is there someone out here that would like to pick up this glove?

By the way, I'm on vBulletin version 3.8.2.

Thanks in advance
