These parameters are on my todo list for the FAQ, but I've had no time to
update it lately... :(

That list of parameters matches mine.

While you need to have memory_limit and post_max_size greater than 
upload_max_filesize, it shouldn't have to be that much larger!  I think
you might have a problem somewhere, or a *very* large install of php.
That would worry me some...

Ditto.

"TAD (Technology Attachment Disorder) is an unshakable, impractical devotion
to a brand, platform, product line, or programming language. It's relatively
harmless among the rank and file, but when management is afflicted the damage
can be measured in dollars. It's also contagious -- someone with sufficient
political clout can infect an entire organization."
