This usually means your images are saved in the wrong resolution (typically the default 
resolution of 72 dpi). This is fine for the html version of the documentation.

The printable documentation however requires your images to have physical dimension 
information encapsulated. Most image manipulation programs allow you to alter this, either 
by directly specifying the print size for the image, or indirectly by specifying a resolution in dpi 
(dots per inch).

The relation between pixel size, resolution and print size is this:
print_size (in inch) = pixel_size / resolution (in dpi)

Does this help ?
