Images from websites are generally low resolution (so that they can be downloaded easily) but they are not very suitable for projection and enlargement on Interactive Whiteboards.
The number of pixels (photos are made up of tiny squares called pixels) on these internet images are relatively small. You can take your own photographs in a higher resolution (more pixels means greater detail) so that they can be used with digital projectors and interactive whiteboards, enabling you to zoom in on areas of an image without losing quality.

See section on ‘Image Size’ for further advice about using various photo resolutions. An image with fewer pixels will become blurred as you try to enlarge it.
