There may be a problem here, but the example pages at the Orca home site
work and this is using the latest Orca release.

For example, check out

http://www.gps.caltech.edu/~blair/orca/orca-example/o_disk_runp_c0t6d0,o_disk_runp_c0t10d0,o_disk_runp_c0t11d0-weekly.html 

and click on one of the links at the bottom for Host10 (you'll see one
of
the Orca bugs here that this page lists host10 multiple times).

All of the images on this page are long enough to get the MD5 hash. 
Clearly
this works, so there's something else going on here.  It looks like your
directory structure is similar to the example site, so its odd that it
doesn't work.
