I wanted to create a yesterday report similar to the today report, which
worked ok, but it kept generating images even though I had stale_age for
the report. I fixed this by adopting the stale_age code from
cheetahgenerator.py and putting in a slightly modifies imagegenerator.py
I've no idea how to do pull requests so here is a diff

This is my first attempt at python coding so please be kind :)
