yes, if ur only calling it once than that means the image well always be it's initial value, here's how to properly do it:
assuming c++
Code:
//init code
int main(int argc, char **argv){
int disp_img = 0; //similar to your load_tar
OSL_IMAGE **Images = new OSL_IMAGE[4];
Images[0] = oslLoadImageFile("tar.png ", OSL_IN_RAM, OSL_PF_5551);
Images[1] = oslLoadImageFile("tar1.pn g ", OSL_IN_RAM, OSL_PF_5551);
Images[2] = oslLoadImageFile("tar2.pn g ", OSL_IN_RAM, OSL_PF_5551);
Images[3] = oslLoadImageFile("tar3.pn g ", OSL_IN_RAM, OSL_PF_5551);
while(!osl_quit){
oslReadKeys();
oslStartDrawing();
oslDrawImage(Images[disp_img]);
oslEndDrawing();
if(osl_keys->held.left){
disp_img = 1;
}
//all other img changes based on button presses go here
}
//release images, and quit oslib calls
return 0;

i only have started like 2days ago...and its C i read somewhere about malloc not too sure about how to impliment it though anyway i did this and the psp crashed..i did some simple arrays before using text and had no problems but this is drive me nutts!
