Optimise images (1 MB reduction)

Hi, jlong.

I've taken the liberty of putting serve's image assets though a range of optimisation tools. Image optimisation allows us to reduce the footprint of images - meaning faster load times at no cost to image quality. It does this by finding the best (lossless) compression parameters, stripping embedded comments, and removing unnecessary colour profiles. [See more](http://port3000.co.uk/imageoptimiser-a-github-bot-to-proactively-op).

I found 27 optimisable images, making a 1 MB reduction in size. That's about 70.44% of your total image assets.

Merry Christmas.
