#include <highgui.h>

int _tmain(int argc, _TCHAR* argv[])
{
IplImage *img = cvLoadImage("one.jpeg");
cvNamedWindow("Image:",1);

Check what cvLoadImage is returning. If it returns a pointer to an image or just 0. If it returns 0 you need to check whether you are trying to load your picture from the right folder or not.
Try:

IplImage *img = cvLoadImage("one.jpeg");
If (img == 0){
You did not load the image!
}else{
show the image in "image:"
}
