Currently there are some small things wrong with some of the pictures in the documentation:

http://docs.mitk.org/nightly-qt4/GeometryOverviewPage.html
Last image -> Screenshot of red wriggly line of auto correction

http://docs.mitk.org/nightly-qt4/PipelineingConceptPage.html
Second image -> Couple of pixels on the bottom missing, looks cut off

http://docs.mitk.org/nightly-qt4/QVTKRendering.html
Second image -> Seems to be namespace mitk vs non-namespace mitk, but this is not obvious, also the mitk:: is missing some of the time on the right side
Third image -> The existence times don't seem to be absolutely correct, some things just destroy at a random time? Somebody with a clue might take a look at it
Note: Both images are .vsd files in a tarred archive
