What is kind of image resizing is this forum using?

[faast]

In case you can't see or not registered, I find this image resizing to be very useful: http://forums.teamxbox.com

- it automatically creates scroll bars if the image is too large
- the forum's width is preserved

Is there a mod here that offers this?

I've found 2 here, but neither of them are this: (a) one just displays a small image that says, "Image too large, click here to view" (b) the other is a image resizer -- which I don't need since that will create too much stress on my server.
