I ran into the same problem over the past few days and i fixed it last
night.
For the past two days I had tried everything to get images working on
the statusmap. Until last night...
I had created a PNG using GIMP on Win32 (40 x 40 px) and scp-ed the file
over to my test box running nagios.
I then converted the PNG to GD2 format using the following command:
pngtogd2 pc.png pc.gd2 1 1 (cos i didn't know what the chunk size
did).
I restarted the nagios process and i still had no images on the
statusmap (just the question mark).
I searched through the mailing list archives, the FAQ, the documentation
for over an hour and finally found a note about pngtogd2. Using the
following command:
pngtogd2 pc.png pc.gd2 0 1
solved the problem. Nagios seems to what fully uncompressed gd2 images
- anything else and it just won't display the image - maybe this is an
issue with CPU computation time (i.e. nagios seeing the file is
compressed / too big and just not bothering / unable to render it...
I've only one issue outstanding and that's a problem with the gd2
image... you can see the problem at this URL:

If anyone could advise as to where the problem may be occurring I'ld
appreciate it.
