Update Credits in our Skyline image

[DimsumPanda]

We updated our image with #14, can we update the credits in index.html?

Update this line in index.html:

<span class="aurimas"><a href="https://www.flickr.com/photos/needoptic/13939643805/in/gallery-ebarney-72157686347209143/">Aurimas</a> via Flickr Creative Commons</span>

Feel free to update css if you'd like, but the credits should go to Muzammil Soorma on unsplash.com.

I believe this is the link to the photographer: https://unsplash.com/@muzammilo

I can finish this off.
