I don't really know SFML but if IMAGE is the same as sf::Image, LoadFromeFile is LoadFromFile and : is . (dot) in the real code then it looks correct to me. Why don't you just test and see if it works?
EDIT: Oh and that semicolon on line 2 should be removed if you want return 0; to run only if the image failed to load.
Of course, because Youtube is the primary and only source of information in the world.
What would all the scholars do without Youtube...
And if you haven't even set up SFML yet, why are you trying to use it?
