Easy image resizing in Windows XP
If you don't want to do anything other than resizing pictures, most image editing programs are overkill. Microsoft has a free Powertool plugin for Windows XP which can help. Assuming you have Windows XP, download and install the Image Resizer Powertoy from Microsoft.
The Powertoy is quick to download and install, and is very safe.
Once installed, right click on your photo (or select lots of photos and right click on the selection) and select Resize Pictures, then take your pick from the range of sizes:
If you are resizing images to go onto a webpage, you should usually use the Custom size, and then type in the size of about 500 by 500 pixels - but how large your images are really depend on your webpage's layout and what kind of picture you have.
