SDL wont display .png image

My program opens, without returning -1, or showing the image, and I was wonderng why this happens.

here is my code

Code:

#include <SDL/SDL.h>
#include <SDL/SDL_image.h>

SDL_Surface *buffer = 0;
SDL_Surface *man = 0;

void draw_surface(SDL_Surface* sur, int x, int y){
    SDL_Rect pos;
    pos.x = x;
    pos.y = y;

    SDL_BlitSurface(sur, 0, buffer, &pos);
}

SDL_Surface *draw_img(const char *filename){
    SDL_Surface *img = IMG_Load(filename);

    if(man != 0){
        SDL_SetColorKey(img, SDL_SRCCOLORKEY, 0xFFFF00);
    }
    return(img);
}

int main(int argc, char *argv[]){
    SDL_Init(SDL_INIT_VIDEO);
    buffer = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE);

    man = draw_img("person.png");

    if(man == 0){
        return -1;
    }

    bool run = true;
    SDL_Event event;

    while(run){
        while(SDL_PollEvent(&event)){
        if(event.type == SDL_QUIT){
            run = false;
        }
        }
        draw_surface(man, 0, 0);
    }

    SDL_FreeSurface(man);
    SDL_Quit();
    return 1;
}

Your other SDL functions also return success/fail.
How about checking them as well?

I changed man in

Code:

if(man != 0)

to

Code:

if(img != 0);

I'm not sure if this would help but, when I go to the executable file in windows explorer it closes automatically

Are you sure the image you're trying to load is in the same folder as the program expects it to be? Additionally, to actually get the image to show after you blit it to the 'buffer' surface, remember to call SDL_Flip on it to update the display.(Added that to your code and the picture showed up fine when the file was in the correct spot).

Thanks!
