On further investigation, this works on my development system (windows 8.1 laptop with packages as given in ticket #361 [raw-attachment:sasview-dependencies-survey.pdf:ticket:213 Table]. It does not work however in the exe bundle.

imageviewer.py in the guiframe package seems to be doing the work and is using matplotlib.image.imread to load the files. My matplotlib is 1.3 instead of the 1.1. on the build system. However this code was introduced by Jae Hie about a year ago (probably using 0.98?) so not likly to be cuplrit? Looking for dependencies that might be a problem I found an article which suggests that only PNG is natively supported by matplotlib and that the other formats rely on PIL -- but my system (which works) does not have PIL while the build system (which seems not to work) does have PIL.
