Win XP: Bigger Thumbnails

The easiest way to do this is with Microsoft's free (and support-free) TweakUI utility. You can download it from www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx. Launch TweakUI, open the Explorer item in the tree at right, and click Thumbnails. Here you can adjust the thumbnail size from 32 to 256 pixels square (the default is 96). Do note that a 256 by 256 image has over seven times as many pixels as a 96 by 96 image. You may want to also slide the Image Quality slider to a lower setting, so you don't expend too much disk space caching those extra-large thumbnails. After you've made the change, you'll see larger thumbnails in both thumbnail view and filmstrip view.
