Advanced Web Page Options: Image Zoom

Image Zoom lets you generate a smaller or larger image.

Image Zoom set to 100 keeps the original size (default). 

A zoom lower than 100 will give you a smaller image. For example, 50 will provide you with half of the original size.

A zoom larger than 100 will give you a larger image. For example, 300 will provide you with a picture three times bigger.
