Optimise bedrock's largest images

[alexgibson]

Description

Webpack gives a useful list of the largest images (in filesize) contained in the site. Some of these may just be naturally large, but could some of them be made smaller than the 244 KiB threshold?

[1] WARNING in asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).

I can spot a number of 1Mb+ images in the list (that aren't animated GIFs), plus quite a few that are > 500kb and can likely be optimized
