It's actually something one could theoretically answer. Maybe something to add to the long to-do list for @MicheleNuijten :p
Seriously though, a great number of papers have been retracted due to errors detected thru their images, plots etc. One can infer standard errors from plots etc. and these one can feed into GRIM/SPRITE/statcheck-like methods to validate output. Automateable?

There are already a list of tools that can reverse engineer plots to extract data, or sometimes just summary stats (e.g. from boxplots). See https://academia.stackexchange.com/questions/7671/software-for-extracting-data-from-a-graph-without-having-to-click-on-every-singl?newreg=a7074e06b32948cd909f5da46afcf190 …https://stats.stackexchange.com/questions/14437/software-needed-to-scrape-data-from-graph/72974 …

I know that
@chartgerink and@petermurrayrust are working on extracting data from plots as well! and I think think there is software to check if figures were copied or manipulated -
I ended up writing this summary. Exciting times, hope progress is fast, as I unfortunately don't have time to help out. http://emilkirkegaard.dk/en/?p=7073
