Failed to download source "Libpng"

I'm new to using the terminal but I gave it a shot anyway. Home-brew installed fine, the next step looked like it almost worked but at the end I got an error. This is what showed up. I hope this is more help than trouble.

That's an issue with Homebrew unfortunately. Sounds like a connection error and it might not hurt to try again.
