Thanks again for all help!!!
Where would DNN be without you two???
First of all, this was a FireFox problem only, (normally IE that plays up.) so the padding I put in worked fine in IE - but had no effect in Firefox.
Anyway....
The CSS class works fine Lee. I thought I needed to put the Style manually on all images but it obviously apply to all images installed.
There is one funny thing though;
The "Hover setting" highlights an area on this image buttons, this area follows the padding - thus shows something sticking out when hovering over the image.
