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. -- -- Dan Nessett _______________________________________________ MediaWiki-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
