There is a neat feature in Vista which displays and image file's icon as an actual thumbnail of the image. I have found this to be extremely useful. But you can also add this feature to your current system [Windows 98/98SE/ME/2000/XP] and the cost is <img src=/S/free.gif border=0 alt=free width=30 height=15>.
You can read about it and download your own copy here: Xentient Thumbnails (Freeware).
<font color=red>WARNING:</font color=red> You will need to disable/pause your Antivirus program before installing this program. I'm running Kaspersky and it blocked one of the files from installing on my first attempt. After I installed this program successfully I did a quick scan with KAV and my system is clean. Thus use your own judgment re: installation. <img src=/S/wink.gif border=0 alt=wink width=15 height=15>
