In order to reduce the image size you have to use some photo or image editing software (XP Pro is just the opperating system). If you let me know what you have got then I'll try and guide you through it, or if you want to try yourself then follow these principles.
Look in the menu's for something that will let you RESIZE or edit the IMAGE SIZE in pixels. Aim to reduce this to around 640 X 480. Usually if you change the horizontal, the vertical will change to suit so you don't end up stretching the picture.
Let me know how you get on.
