Small note: When migrating a site or having permissions problems related to ImageCache images not being created...
Interesting discovery with Drupal's file uploads today. We created a microsite that users can upload video to. These files could be 30MB or less... At first I believed this was a small change to our php.ini file on our server changing the following:
upload_max_filesize = 30M
post_max_size = 30M
