Adapting the demonstration of a program execution without modifying the program code by providing application hooks in the program to display user selected images

A computer program product embodied in a machine readable medium for selectively displaying images during the execution of an application comprising the programming steps of:

• executing an application, wherein said application contains multiple application hooks inserted at appropriate locations in the code of said application, wherein said application hooks identify respective ones of multiple images in a configuration file;
• executing a first application hook to call said function;
• retrieving a selected first image located at a first file name from said configuration file responsive to said first application hook during said execution of said application;
• and
• displaying said retrieved first image during said execution of said application.

A system, comprising:

• a processor;
• and
• a memory unit coupled to said processor, wherein said memory unit is operable for storing a computer program for selectively displaying images during the execution of an application;
• wherein said processor, responsive to said computer program, comprises:
• circuitry for executing an application, wherein said application contains multiple application hooks inserted at appropriate locations in the code of said application, wherein said application hooks identify respective ones of multiple images in a configuration file;
• circuitry for executing a first application hook to call said function;
• circuitry for retrieving a selected first image located at a first file name from said configuration file responsive to said first application hook during said execution of said application;
• and
• circuitry for displaying said retrieved first image during said execution of said application.
