Small image files can be embedded in Python code using the base64 encoded string of the image. If you have to present a number of small fixed images in your program, embedding might be easier than including a set of image files. Attached files can be lost, and than your program won't work. The snippet uses the ever popular jpeg image and wxPython to display the image. I have used a panel here, but you could also use a button or a label.
For your sanity, you do not type the image string, you let a small Python program create it, then copy and paste it into your code. For an example how to do this see:
