Corrects image size in web.pdf - issue 982

Corrects image size in web.pdf - issue 982
This patch updates all the macros.texi files
to change the macro for exampleImage. It now
uses an image with greater resolution and 
forces the width to 6 inches to fit onto the
page.  This is a first step towards making
learning.pdf appear more professional.

Please review this fairly simple change to improve the example images in
learning.pdf

LGTM, but do we still use the -small images for anything else now?  I mean, go
ahead and push this, but then please investigate if we still need the -small
images, and if we don't need them, then please remove them from the build
system.

Yes - they're used in the web pages, with a link to the big ones that can be
