Good catch. This example is located at Basics › Web › LoadingImages

Incidentally, the corresponding live sketch is also broken.

The file "https://un5qen5p9khp3d565kgverhh.julianrbryant.com/content/1-home/processing-web.png" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.

I found processing-web.png on the Wayback Machine here.

Shall we host it on processing.org and update the example?
