Unless you've done something really weird the most likely possibilities
here are:

1) convert is not in the PATH that the web server sees. For instance, if
you install ImageMagick in /sw/bin or /opt/local/bin (fink or MacPorts,
respectively), this is NOT in the default system PATH variable at
startup -- it'll probably have been added to your *user* shell, but
Apache won't see it when started on boot.

You can easily work around this by adding it to the path in your
LocalSettings.php, something like:

putenv("PATH=" . getenv("PATH") . ":/opt/local/bin");


2) General file permissions on the image directories causing a failure
to be able to create the thumbnail images. Double-check the file and
directory ownership and permissions in your 'images' dir here.
