Photo upload and cropping PHP class

/**

• Description of Photo
• The purpose of the class is to take an image that has been / is being uploaded through a http upload
• The various validation methods will still need to be observed and created as the class does not handle that
• Largely due to the fact that certain restrictions may change from program to program
• This class can take the uploaded image, move it and rename it.
• It also can take the image and make a square crop of the image.
• The class can also resize the image while keeping the original ratios
• PLEASE NOTE:: the gd lib is required for this (sudo apt-get install php5-gd)
• usage :

• create the object and pass it the image

• $photo = new Photo($image);

• set all the variables needed to process and save the image

• $photo->set_orig_name($_FILES['file']['name']);
• $photo->set_new_name(time() . '-' . md5($email));
• $photo->set_orig_dir('uploaded_files/full_orig/');
• $photo->set_cropped_dir('uploaded_files/');

• call the function that will move and save the origianl photo

• $photo->save_orig();
