Missing input images for PShader tutorial 10.2

I was studing the PShader tutorial, in particular the textured point sprite example 10.2 (Sketch that renders sprites using a custom point shader). It refers to three input images (cloud1.png, cloud2.png and cloud3.png). However these input images are not downloadable from the website. And (unfortunately) it seems these PShader examples are also not part of the Processing download. The solution for this issue would be to make the three images available / downloadable from the website.

In a broader sense, it may be a good idea to add examples from tutorials to the Processing download. Perhaps the developments with regard to the Example Manager may facilitate this.
