During the meeting last night I proposed fixing only those images where the difference was most significant (>50% reduction in size and files of at least 32Kb). The results are here: https://github.com/johanvdw/OSGeoLive-doc/tree/compresspng The result can be downloaded as a package from: https://launchpad.net/~johanvdw/+archive/ubuntu/osgeolive-docs-compressedpng And it can be previewed at: http://gisky.be/osgeolive-docs/en/index.html In total we save some 34 Mb, most of which is preserved when compressing the files. Since I did not see any image which is not good I propose to merge this.
