Where did my images go?

I am using my own project GitHub - andytriboletti/openspace-swift: Open Source Space Game on a new computer and Github desktop. I noticed all the images are not large enough to be images. Where did the images go? I tried to also download the zip. The images are all like 130 bytes, not image file size. I maybe did something with Git LFS?

I installed git-lfs and it worked. Thanks for hosting my stuff, GitHub!
