That's what I've always done. You see, my computer really sucks, so I am forced to find the ghetto way around doing things. I have enough time to go make a meal for myself in between my clicking on the PSP icon and the program actually opening for me, so IE suits me just fine. Until it crashes.

I have Windows 98 and it allows me to preview images in any folder without even having to open any programs. When you're in a folder, just go to View >> as a Webpage, and select it. You'll be able to see a mini-version of your image simply by clicking on it. This works better for smaller images though. I'd imagine it really shrinks wallpapers and stuff down bad.
