Any public http images available?

If you actually open that URL above in your browser you can see that it is a tiny text file, a so-called iPXE script. It is just a normal text file. You can create it in any editor and host it on any web server.

I just install Apache on my own Linux server and put the files in /var/www/htdocs/. I then try to load the URL in my browser. If I can see the text file there, you're good to go for making a script load by iPXE.

For more information on scripting and how to load the first script, you'd really want to look at the chainloading article on the main website, and the very extensive scripting documentation.
