The screenshot viewer is now available! Only tested on Windows for now so Linux/Mac users (who make a good proportion of visitors to this site) be warned. I have created a Google code project for all the code on this blog at http://code.google.com/p/daftpython/
You can get the latest Screenshot viewer here. It is a single .PY file tested on Python 2.6.6 and wxPython 2.8. We have been trying out a CXFreeze version with a Windows Installer and it is looking good. I'd like to look at maintaining aspect ratio for the thumbnails and display.
If you run it on a non-Windows platform I would appreciate a screenshot. Any other thoughts, please leave a comment!
