On Windows 7's new file layout in Explorer. Some PNGs will show the size whereas others won't. I've tried rebooting and clearing the cache, but it doesn't work. Also, all of these images were saved with Paint.NET, so I am sure that the size isn't embeded in the file, and if it is, it appears that Windows doesn't go by it. The ones without sizes are 300x300. Is there a maximum size before it won't show the size anymore?
