PHP - existing site - 2 to 3 small changes

I have an existing PHP driven website. I need to fix a few new features on this site. I have an image cropping feature on the site. I need the following changes: 1) On the crop screen, I will need to change the dimensions of the crop. I will give you the new dimensions 2) On the crop screen, I want the standard crop drag area to be similar to the canvas used to display the image (the canvas is not rectangular) These are the main two items. Send me a message to get the site URL
