At least with some versions of php, if *upload_max_filesize* has a larger value than *post_max_size*, file uploads bigger than *post_max_size* but smaller than *upload_max_filesize* fail without triggering a helpful error message for php to detect and report. (This may be fixed in recent versions of php - I'm not sure.) So the general advice is to set up php with the two values the same or make upload_max_filesize smaller.

Andrew, Thanks for taking the time to explain that a little more for me.
