how do i know if the loaded image was successfully loaded?

like i want a warning that this image wasnt successfully loaded. I know this can be done by creating a sprite but i dont want to check it myself. i think there is a code for that..

anyone?

i think there's a function called dbImageExist ( ID );, just call it after loading and see if it returns true (exists, load was ok) or false (doesn't exist, failed to load)

i remember some guy called Diggsey or something, he made some error handling system a while ago..
oh here it is

load.cpp

+ Code Snippet

int load_main_menu(int image, int max)
{
	dbLoadImage(image_main[image], image+1);
	
	//check
	dbSprite(image+1, 0, 0, image+1);
	if(dbSpriteExist(image+1) == 0) // ERROR/FAILED
	{
		dbDeleteSprite(image+1);
		dbDeleteImage(image+1);
		return 2;
	}
	else						    // SUCCESS
	{
		dbDeleteSprite(image+1);
		return 1;
	}
}

main.cpp

+ Code Snippet

		if(load_main_menu(loaded_image, main_menu_images) == 2)
		{
			dbSprite(loaded_image+1, 0, 0, loaded_image+1); //Visual Checking but is not necessary at all
			dbWait(3000);
			break;
		}

i figured it out in such a very easy way but i am doubtful, as i have tested it work fine but i dont know it you guys will say ok for this.
