I was able to get the images to work by doing the following:
Edit User.php which is in public_html/rosariosis/modules/Users/User.php
On line #379, removed the comment code. I also added the .png and .gif to the array:
$new_photo_file = FileUpload('photo', $UserPicturesPath.UserSyear().'/', array('.jpg', '.jpeg', '.png', '.gif',), 2, $error, '.jpg', UserStaffID());
On line #386, I added .jpeg, .png, and .gif to the array:
#381 $new_photo_file = ImageUpload(
#382 'photo',
#383 array( 'width' => 150, 'height' => '150' ),
#384 $UserPicturesPath . UserSyear() . '/',
#385 array(),
#386 '.jpg','.jpeg','.png', '.gif',
#387 UserStaffID()
#388 );
