WMS Layer Problem

Yes, that URL from the Tomcat log is probably the one that Mapserver 
used to request the photo layer.

Recall the error message I mentioned before said "Invalid Lon-Lat 
coordinates, must specify at least one (lon,lat) pair correctly; 
Longitude must be between -170 and -60 Latitude must be between 15 and 
75 ". The bbox in your URL is outside that range.
