It's done in .htaccess

Try doing a forum search for max upload, there's probably an answer already posted...

for what it's worth, here's what I'm using:

Code:
php_value upload_max_filesize 100M 
php_value post_max_size 100M 
php_value output_buffering on 
php_value max_execution_time 1000 
php_value max_input_time 1000 
php_value session.gc_maxlifetime 14400
