works great, but useless on retina screens

Small, simple app, does exactly what it needs to do.

Unfortunately, on my retina macbook, the app is useless, since it only shows some small part of my photos on a gray background.
(To check that it’s really a retina issue, I set my screen to regular, non-retina mode, and it worked fine then)
