I always forget how to fix the maximum file size for uploading on drupal. Simply add this to your .htaccess file (which goes in the main folder of your drupal installation):
php_value upload_max_filesize 75M
php_value post_max_size 75M
php_value memory_limit 32M
or this for your php.ini file
upload_max_filesize = 75M
post_max_size = 75M
memory_limit = 32M
