A video note to remind me how to show super-sized icons in the Finder of Mac OS X 10.5 Leopard (I read the tip by Rob Griffiths on MacWorld).
I show filtering the icons by using "jpg", note the jpg is within the double quotes. Filters can be by "jpg" OR "png" to only show both those image types. The search can also be saved to the Finder Sidebar if it is something you will want to use again.
I show the tip using photos but it works well with any icons from applications that saves meaningful thumbnails.
