I recently got a CD-rom from a hospital containing X-rays of my leg to share with my doctor. Upon finding a computer with a functioning optical drive I was dismayed to discover that the CD-rom contained not 3 simple images of the bones in my leg, but almost 400 megabytes of impenetrable binary data in over 30 nested directories and an .exe called MedicalImageViewer which I was unable to run on the latest version of Windows in my posession (win7) due to missing visual basic related dlls.
I was eventually able to run the app on a friend's computer, but finding no in-built option to export the images I was forced to take screen grabs to email to my primary care provider.
