Dear everyone,

I am building a custom module where I have added a menu for the user to change the personal photo he/she uploaded during registration (using $Form and file_save_upload, etc) . I am using Manual Crop module which triggers when the user hit "Upload" during registration. However, I want to transfer this functionality to my custom module so that the user can crop the new photo he uploaded. The problem is I do not know where to start and how to interact with Manual Crop module from within my module. Can someone point me to the direction on how to accomplish that ? Thank you all in advance.
