I think they are small because of the size they were saved. You may have to go back in and re-save them at a bigger size. They are saved at 96x73 pixels. The picture below shows a photo saved at 600x450. If you right click any picture and choose properties, it will tell you the size that it was saved. If you are using a digital camera, check your camera settings to see if you have the camera saving pictures at the smallest size when you are taking them. Some cameras have this feature so you can take more pictures and use less room in the camera itself. Otherwise, you'll need to check your settings in whatever program you use to save the pictures to your computer.
