Make sure that the program is not terminating on the "return EXIT_FAILURE" line, which would mean that it failed to load the images.
Found the error, it was .png not .jpg... now it open well
Thx...
EDIT: i found a new error, when load my background.png (an image 2000x1250) it say me this error "Corrupt PNG".
What is that? Is too big for SFML? O.o
