Here's a cool power toy I found for Windows XP. It will resize your pictures. It's very easy. If you can right click, you can resize pictures!

here are the steps to resize
- Install the file from the link above.
- Open an Explorer window and select all of the images you want to resize.
- Right-click on one of them and select "Resize Pictures".
- Select "Medium" (800x600) or "Large" (1024x768) and then click "OK". The images you selected will now be resized and will be given new file names that include the size you selected (ex. "IMG_0845" will become "IMG_0845 (Medium).JPG").
This utility if free and works great ! You will save yourself a lot of gallery space if prior to uploading the pictures you will resize them first.
