In the case of providing a variable data print, it is an object to provide an image processing apparatus in which the user can take a countermeasure against an error more rapidly. When a variable data printing process is started, whether or not image data is inaccessible is discriminated to all image data used in the printing process. If there is the inaccessible image data at this point of time, the user is notified of it and the printing process is cancelled. At this time, a path name of the image data and a name of a record to which the path name belongs are simultaneously displayed and such a record is directly previewed.
