(1) Dropbox link: 3.5 x 5.5 " box enclosing 
illegible fine prints at 100%.  To my surprise, when I increased it to 125 
and 200%, the box actually shrank to smaller sizes.
 
(2) Google link: a box with blue borders appeared 
on the left with another adjustable area on the right.  Prints were small 
and became blurred when the box was increased.  The right half of the box 
went off the monitor.
 
(3) Click on the picture:  appears to be the 
same as Google click.
