3 pixels jog now on FF too?

I'm having this issue with FF...
HTML code



CSS code

#right-side{ width:637px; float:left; }


The doctype is:

My version of FF is 2.0.0.2.

The problem consist in that FF is adding 3px at the bottom of the image [ to other images in the same page as well ], making the container [ right-side ] be of 446px height instead of 443px as it should...

I'm really stuck with this... Any idea is appreciated.

Thanks!
