Loading background staff images on about.gitlab.com makes a lot of unnessesary requests
Loading background staff images on about.gitlab.com takes a long time. There are 110 images and they take 6MB of data to send. The image could be done more efficiently as a single image, pre-generated at site-build time (e.g. using imagemagick). Or, if this prevents the layout from being 'responsive' then it can be tiled into groups.
Not only that, but I imagine it also causes a bit of nasty request amplification on the server side. Letting servers handle less requests can let them get busy doing other work.
