Uploading two images, re-sizing, and saving to database with CodeIgniter

Question

I am trying to upload two images, re-size them, and then save them in my database but am having some problems. I have posted my controller below. When I print_r() my $db_info array I am getting values for photo_one and thumb_one, but nothing for photo_two or thumb_two. When I print_r() the $_FILES array everything is in there like it should be. Can anyone see something I am missing that is preventing my controller from processing the second image? Thank!

I was a victim of overlooking beginner mistakes. I named my method for uploading images the same as the upload class. Therefore when I called for the class, things were getting mixed up. Lesson learned and problem solved.
