If you're looking to know what the images look like you should use a font viewer like Typograf, Font Navigator or Font Thing. Or simply type out a full character set on a page in any word processor or illustration program, then with your wings and dins installed ant the text selected, change to each font and print the page.
There are actually some good images in those fonts that you would never guess. One day, a slow day, I sat down and typed every character on the keyboard (upper and lower case) then went through my entire font collection and replaced the characters with the graphic fonts and printed them out for reference. There are some great ones: geographic symbols, multiple MiniPics, Plants, media, food, animals. IF you have free time, I would suggest it.
