Are your pictures too big for the web? What to do? If you r running a legit version of Windows XP, it's easy. (The website may want you to validate your Windows OS in order to download the powertoy.)
The download will install another item to your context menu. (pop-up menu when u right click a file or pic)
Go to this page and download the Windows XP Image Resizer Powertoy. Once installed, it will let you batch resize an entire folder of pictures by right clicking on a multiple selection within My Computer. You can also resize a single picture.
Upload the small size setting pictures (640 X 480). It compresses them as well for a web safe, file size. Make sure you dont check resize originals though, under the advanced tab.
