Your add-on breaks the ability to show pictures such as JPG in the browser (direct link to a jpeg, in its own tab, not on a web page).

Confirmed that the pics display correctly as soon as I disable Zoom Page WE, and break as soon as I re-enable it.

When I look at the page information, Firefox reports that the picture is 0pt x 0pt big.

Please fix (or remove "picture zoom" altogether, since this is not really why we install Zoom Page WE)
