[Phpwm] displaying images on screen

[Phil Beynon]

If worried about popup blockers you could use an iframe instead and call the 
php routine effectively on a seperate age. That also gets around page 
definitions being needed to be altered etc and quite possible means no 
javascript requirement. Also as it is seperate from the page being iterated 
then it can do things once the main page has finished being rendered.

Also... adding a small random spoiler code at the start of the filename to 
get around browser caching issues is a good idea as well. E.g. "picture.jpg" 
becomes "x34tpicture.jpg"
