To see what happens, I tried to convert the file manually from my command line prompt. The command I used was
convert -thumbnail 600x600 International_Space_Station_Space_Shuttle_Atlantis_Sun_Transit_2010.png thumb.png
It worked perfectly.
Might there be a problem related to the long file name?
I don't think so.
Try increasing the values $wgMaxShellMemory, $wgMaxShellFileSize, $wgMaxShellTime
You can also enable debug and look for the line doTransform:Running custom convert command xxxx to find the exact command that is being run.
Thanks. I will try all of these suggestions and report back.
However, I did some research and it appears there is a long-standing (over 3 years) bug that reports problems producing thumbnails for large png files (see https://bugzilla.wikimedia.org/show_bug.cgi?id=9497). This bug is still open, so it is possible I have run up against an unresolved problem.
