Chuckle.
The pixels coming out of one of my cameras are twice
the diameter of the pixels from the other two.

LOL, I was thinking that I didn't want the file size.
Should read pixel count.

What OS? In XP's Windows Explorer you can at least right-click the
column headers and add Dimension then click it to sort by the first
value.

More or less true, all other things being the same. But several
of my cameras offer 2 or 3 compression ratios for the same
resolution (pixel count), so if different selections have been used,
or if you're mixing pictures taken with different cameras that don't
compress similarly, file size won't accurately reflect pixel count.

You are correct Dave. I meant pixel count.
I have 300 plus images of different shapes and sizes that need to be resized
for a website.
I did a quick resize using Irfanview of all images to be 300 wide.
When I use each image I resize again to be 280 or less high.
I want to identify which ones are less than 300 wide. Then I can resize
correctly, at 100% quality, not the 80% that my setup was set to.
I want to sort them so that I can bulk resize the 300 wide images and then
hand resize the remaining images.

You got some good answers for pixel count. I especially liked Markeau's
answer. I did not know about all those options.

If I had XP I would agree with you Joseph.
I have Windows ME.

Anyway of saving that displayed information?
I don't want to Control Print Screen numerous times.
I don't want to type every one into a database.
