As with any PHP file upload routine if you run into problems with big file uploads check these settings with phpinfo();:
upload_max_filesize
max_execution_time
file_uploads
post_max_size
On my web host I can set them to higher limits by placing a php.ini file in the folder with the upload code with these settings:
upload_max_filesize = 5M
max_execution_time = 60
file_uploads = On
post_max_size = 6M
upload_max_filesize
max_execution_time
file_uploads
post_max_size
