Indeed, IE has issues with PNGs, but FF has issues with everything when the system is using 8-bit color.

Expanding the page is not a broken table. A broken table is a condition in which the elements of other cells in a page are rendered incorrectly due to an unexpected size in another cell. IE renders all cells in all tables correctly regardless of the size of any image posted.

How can a static image be proof of adjustment?

I was talking about a Windows GUI element that any similar program is expected to have, but FF is strangely without.
