Error: Error: useless setTimeout call (missing quotes around argument?)
Source File: http://www.sined.co.uk/tmp/popmain.htm
Line: 19

This tells me that the error is in the "setTimeout" call, so check the 
syntax of that function.

Looking at the syntax of that call, and googling for that function, the 
function name in the setTimeout call should be in quotes, or the params 
should be passed differently:

setTimeout( "window.document.popMain(imgs[i])", 500 );
setTimeout( popMain, 500, imgs[i] );

However I was having problems with those, and there seems to be a lot of 
contradictory opinion on various websites - how unusual.

So I tried to do looped images with a different approach at:

http://www.sined.co.uk/tmp/popmain.htm

Which seems to be working in my ubuntu/firefox, doesn't use innerHTML, 
uses dom node and element property manipulation.
