Adding simple image display to a pascal game

Hi all,

I've written a baseball game that runs in a simple text only window (I
think it's technically called a command window).  I'd like to add the
ability to also popup a second graphics window that I can display
images on to complement the game logic.  For example, when my game
announces a new batter has come to the plate in the text/cmd window,
I'd like to also popup a 2nd window that I can display an image of the
pitcher and batter on.  I've been researching for a few days and can't
figure out how to do this, or if it's even possible! 

What would be fantastic would be if someone could point me to some
very simple code that I can embed in my pascal game to display an
image on this 2nd graphics window.

My current environment:
Lazarus 1.2.6
FPC 2.6.4
Windows 8

Thanks!
Dennis

For a pop-up window create a form. You may wish to set borderstyle to
bsnone.
Then fill the whole form with a TImage object (from the palette).
Then create a temporary TJPEG object to load the image from the file.
And finally:
form2.image1.canvas.copyrect... from the loaded TJPEG
form2.show
and form2.hide ontimer or onclick depending on the idea.
