That's neat... thanks a million!!!

It works perfectly, and in a MUCH simpler manner than my feeble attempt.
What's even better, now I understand how intermaps work, and they're pretty 
powerful... I can think of other applications for it, now that I've seen the 
light! :-)

I only had one problem: I created local/localmap.txt but the "LargeImage" 
parameter wasn't being passed on. I then modified /scripts/intermap.txt 
(adding the line you indicated) and it worked. Should I enable 
local/localmap.txt explicitly?

In fact this is not an issue, as it works just the same.

Thanks again for your help Patrick, and especially for pmwiki... keep up the 
good coding!
