hello,

i’m going bananas here, somehow below all of my images in my page there is a gap, a margin wich isn’t there in the code. Even Firebug can’t see it but Firefox and Safari are rendering it - EVEN WITHOUT CSS AT ALL!

Never happend to me before...!

Sometimes it can be due to whitespace in your HTML, as shown in this other answer.

well, got it.

it was a conbination of

font-size: 0px; line-height: 1;

This is actually not that uncommon. There are plenty of questions already about this, and it's of course because the image is an inline elements so there is some space between the bottom of the image, which is placed on the base line of the text, and the bottom of the text line.

The easiest solution to this is to simply use display:block; to turn the image into a block element. Floating the image using float:left; or float:right; also works as that also turns it into a block element.

Adjusting properties like the vertical-align, font-size and line-height may also affect the distance, but it's not as robust as it doesn't really remove the effect. It might still appear in some circumstances.
