This was something of an unfinished discussion from last year. I had 
left the docs untouched in the hope that it would get fixed. Basically, 
when the extent caching was added, it made the extent calculation (done 
using imagesize) manditory. The old code would load the image regardless 
of if it was on screen if there was no imagesize, and would load 
onscreen maps if we knew the imagesize. I think the old behavior is 
desirable, or the imagesize should be calculated by opening the image 
when indexing. (like the identify command)

As things stand now, we just totally killed compatability with WinAPRS 
.geos with this requirement. I nominate this for a "blocking release" bug.
