Well i'm guessing you just want to display the image, at the moment you load it, then exit the program, so quickly you can't see anything.
Therefore if you want it to pause after loading the image, the code should look like this:
Rem Project: Test Gaspode creations
Rem Created: 30/10/2003 22:40:42
Rem ***** Main Source File *****
LOAD BITMAP "Gaspode creations.tga"
rem Loop around and around infintly until you press escape
do
rem Updates the screen to show your image
sync
loop
Though if you're going to be doing a 2d platformer, i suggest using sprites, sort of like this:
Rem Project: Test Gaspode creations
Rem Created: 30/10/2003 22:40:42
Rem ***** Main Source File *****
LOAD IMAGE "Gaspode creations.tga",1
rem Loop around and around infintly until you press escape
do
rem SPRITE, sprite number, x position, y position, image number
SPRITE 1,0,0,1
rem Updates the screen to show your image
sync
loop
Unlike bitmaps, you can move sprites, do collision...etc
Good luck!
