[Issues] failure to produce inspect images

[Koen Kuijken]

I am unable to produce inspect images for coaddedregriddedframes or gaissianizedframes.
I am running the master awe on nieuwland.astro.rug.nl (tried develop and the result is the same):

nieuwland.intra.astro.rug.nl>which awe

awe> 

Looking at the ThumbnailPlot.py code it seems that DPI is equal to 'figure' rather than a number as expected. The call that sets DPI is
        DPI = pylab.matplotlib.rcParams['savefig.dpi']

I could fix this by first setting 
pylab.matplotlib.rcParams['savefig.dpi']=100
before calling the get_inspect_images() method.

But then the next error occurs, in add_colorbar(), and that one I cannot fix easily.

Is this related to the warning about the version of pylab that I get on startup?
Do I need to change something in my environment or is this something you can fix?
