# This algorithm collects all image
# versions of a package and determines the (second) newest version.
# E.g. if there are version 1.0 and 2.0 and the user is looking for
# a screenshot of version 1.5 then the 1.0 version is returned.
# This way the user does not see a screenshot of version 2.0 because
# 2.0 might contain features that were not there in version 1.5.
