image dimensions missing

[robm2002]

When highlighting an image in Finder, the dimensions no longer show in the right hand window for certain images. This is since I upgraded to Lion. Anyone have any idea why this is happening?

Your graphics files are icon files in fact. Your "new" behavior appears to be standard behavior for icons. To the best of my knowledge, it was ever thus.

I assume that this is because icons are not single bitmaps, but a file holding various resolutions of the same icon. In this case, it makes no sense to display a bitmap dimension because there are several.
