20120403 - The Problem:
In FF (fedora 16 version 6.0.2) a faint border shows up at the right of some images
This does not happen in Win7 FF version 7.0.1 OR in Win7 MIE 9.0.8112

Example img_border_prob-i1.gif:
(In FF the problem border should show up on the right of some (not all) of these at some (not all) page zoom levels).


 / Item-i1  / Item-i1  / Item-i1  / Item-i1  /


Example img_border_prob-i2.gif:

 / Item-i2  / Item-i2  / Item-i2  / Item-i2  /


Example img_border_prob-i3.gif:

 / Item-i3  / Item-i3  / Item-i3  / Item-i3  /


Ah HA! The problem is that the image in i1 has a color background that runs to the side of the image.
In i2 the background is opaque and the colored part is stopped at 1px from the edge of the image.
In i3 the background is opaque BUT the colored part is touches the right side.
So I guess FF decides it needs to clarify an images edge if it is all image.
