Now that I have the base functionality that I'd use/want I need to refactor this code so its easier to maintain / update and add.

right now I'd like to with time permitting to:

• move the directory logic into a class or method. IE this stuff:

if ( $directory == 'index' ) {
  $fileList = $filesystem->listContents( null, false );
} else {
    $fileList = $filesystem->listContents( $directory, false );
}  

if ( $directory == 'index' ) {
  $newImagePath = $filesPath . '/' . $newImageName;
} else {
  $newImagePath = $filesPath . '/' . $directory . '/' . $newImageName;
}  

if ( $directory == 'index' ) {
  $uploadDir = '';
} else {
  $uploadDir = $directory . '/';
}

• move the flysytem stuff into its own class so we can easily reuse it "more better"

• add optimized, optimized renamed, and uploaded files to the file list from the json response retrieved from the ajax endpoint
  *add option to delete a directory

• add option to copy/clone an image

• add metadata preservation options to the image upload

with time permitting move to a service

clean up templates - they are currently a mess and I know what they do since I built them :) haha
