[SDL] Images wont display
Author
alright im still working on this program and for some reason none of the images will load. i believe im using all of the correct functions please help.
here is the code so far.
Have you tried using the error description function SDL_GetError() to determine what the problem loading the images was?
Also, you should load your images once, outside the loop. Like this:
You should include the error checking after the calls to SDL_LoadBMP but before the loop.

it doesnt return an error, but it still doesnt display the picture its just a big black screen. but thanks for the help.
You don't seem to be using SDL_Flip(screen). Try putting that at the end of your loop.
Also, SDLK_DOWN is a constant, not a variable that changes value when a key is hit. You either need a SDL_PollEvent() loop or to use SDL_GetKeyState() if you want to react to keypresses.

Add
SDL_Flip(screen);
after you blit the surface.
That should get your image on the screen.
Good luck!
