[Plugin: Profile Pic] After uploading the profile pic , page will redirects to error messages

These are the error messages:

Warning: Invalid argument supplied for foreach() in D:\xampp\htdocs\wordpress-mu\wp-content\plugins\profile-pic\profile-pic.php on line 422

Warning: Cannot modify header information – headers already sent by (output started at D:\xampp\htdocs\wordpress-mu\wp-content\plugins\profile-pic\profile-pic.php:422) in D:\xampp\htdocs\wordpress-mu\wp-includes\pluggable.php on line 890

I added this if condition before foreach statement at 422 line in profile-pic.php and it is working fine now.
