Problem with Gallery Image Uploading

[eluser]jshultz[/eluser]
I've got an image uploader that doesn't upload images. I'm not receiving any errors and i've checked the folder permissions and even on 777 no images are getting uploaded.

You can see the code here: http://pastebin.com/Wzu4gyed

The value for gallery_path is /home/domain/public_html/assets/images/gallery

The value for gallery_path_url is http://domain.com/assets/images/gallery/

I have used this same code on another site with zero problems. I'm not sure what the problem is with this site?

Here's the message I'm getting from var_dump:

The upload path does not appear to be valid. You did not select a file to upload. array(13) { ["file_name"]=> string(0) "" ["file_type"]=> string(0) "" ["file_path"]=> string(0) "" ["full_path"]=> string(0) "" ["raw_name"]=> string(0) "" ["orig_name"]=> string(0) "" ["file_ext"]=> string(0) "" ["file_size"]=> string(0) "" ["is_image"]=> bool(false) ["image_width"]=> string(0) "" ["image_height"]=> string(0) "" ["image_type"]=> string(0) "" ["image_size_str"]=> string(0) "" } string(48) "/home/verdebus/public_html/assets/images/gallery"

I checked the file extensions and they're correct. i've tried hardcoding the upload path, removing /home/verdebus from it and just using /public/html/assets/images/gallery and that didn't work. and i've tried it with and without a trailing slash. still no go.
