Reading Wesley J. Chun’s excellent Core Python Programming I realized I could definitely improve my wallpaper checker, at least internally. That’s what I did today, and aside that, I added an option to view a thumbnail of the images contained in the lists. Note that it is not meant to be an image viewer, just a way to show the images in the list (and I suggest you filter it first if it’s long). The image viewing part is my first try with Tkinter, the Python module to create interfaces using Tk. It’s ugly looking, but at least it works.
