    Cool Image over the whole screen!

    Hi, well since I got more familiar with header files and libaries from my last project with SQLite (ended up well ) I had another crazy idea! I want to create a prog. which would show a 1024*768 image over the whole screen when I run it. Can somebody point me to a good libary? Because I searched at Google but I got so many of them that I don't know what to use? Can I do his from command line, because I hate the Win API I work in DevC++...maybe someone knows a good Devpak?

    I managed to fix everything you rock man, the only prob is, when I display a bitmap it appears in a window, how can I show it over the screen? Like a PowerPoint presentation...just a example to what I want to do...

    Just pass the flag to SDL_SetVideoMode()
    Code:
    SDL_SetVideoMode(640, 480, 32, SDL_HWSURFACE|SDL_FULLSCREEN);

    OK next question, here the code:

    Code:
    #include "stdlib.h"
    #include "SDL/SDL.h"
    
    int main(int argc, char *argv[])
    {
    	SDL_Surface *screen;	//This pointer will reference the backbuffer
    	SDL_Surface *image;	//This pointer will reference our bitmap sprite
    	SDL_Surface *temp;	//This pointer will temporarily reference our bitmap sprite
    	SDL_Rect src, dest;	//These rectangles will describe the source and destination regions of our blit
    	
    	//We must first initialize the SDL video component, and check for success
    	if (SDL_Init(SDL_INIT_VIDEO) != 0) {
    		printf("Unable to initialize SDL: %s\n", SDL_GetError());
    		return 1;
    	}
    	
    	//When this program exits, SDL_Quit must be called
    	atexit(SDL_Quit);
    	
    	//Set the video mode to fullscreen 1024x768 with 16bit colour and double-buffering
    	screen = SDL_SetVideoMode(1024, 768, 16, SDL_DOUBLEBUF | SDL_FULLSCREEN);
    	if (screen == NULL) {
    		printf("Unable to set video mode: %s\n", SDL_GetError());
    		return 1;
    	}
    	
    	//Load the bitmap into a temporary surface, and check for success
    	temp = SDL_LoadBMP("screen.bmp");
    	if (temp == NULL) {
    		printf("Unable to load bitmap: %s\n", SDL_GetError());
    		return 1;
    	}
    	
    	//Convert the surface to the appropriate display format
    	image = SDL_DisplayFormat(temp);
    	
    	//Release the temporary surface
    	SDL_FreeSurface(temp);
    	
    	//Construct the source rectangle for our blit
    	src.x = 0;
    	src.y = 0;
    	src.w = image->w;	//Use image->w to display the entire width of the image
    	src.h = image->h;	//Use image->h to display the entire height of the image
    	
    	//Construct the destination rectangle for our blit
    	dest.x = 0;		//Display the image at the (X,Y) coordinates (0,0)
    	dest.y = 0;
    	dest.w = image->w;	//Ensure the destination is large enough for the image's entire width/height
    	dest.h = image->h;
    	
    	//Blit the image to the backbuffer
    	SDL_BlitSurface(image, &src, screen, &dest);
    	
    	//Flip the backbuffer to the primary
    	SDL_Flip(screen);
    	
    	//Release the surface
    	SDL_FreeSurface(image);
    	
    	return 0;
    }
    Well can somebody tell me the wy how do I tell the prog. to display this image until I press enter or something? I don't want to use system("PAUSE") , I tried to put getch(); before return 0;, i Included conio.h but the prog. just runed on and right then off? What's the problem?
