Optimise images (415 KB reduction)

Hi, tomafro.

I've taken the liberty of putting tomafro.net'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 26 optimisable images, making a 415 KB reduction in size. That's about 25.16% of your total image assets.

Merry Christmas.
