It works. :-) However, this one apparently uses each pic only once and after that I just get "dummies". Nesting this \dorecurse didn't work (not that I expected it to, but had to try anyway) - how to tell this code either "when you've used up all the photos, start over" or "add any random graphic in this directory"? It looks like I'm going to have 50-100 pages, so if there are 10-15 graphics and they are added completely at random, the likelihood of each one to appear at least once is pretty high (at least according to what I remember of my probability math). Thus I won't need any complicated checkups, any old randomizer in the "take a card out of a bag and put it bag" sense should do the trick; I'm just not used to doing this type of stuff, so I cannot even fathom where to start! Hmm... I'd like to include besides png and jpg also vector graphics in pdf format, but obviously I need to exclude any pdf documents in the same directory. Of course one solution is to put the graphics into a separate directory, but if I only want to included .png, .jpg and .pdf with a certain name (like 33s-sensor.jpg, 33s-cutthrough.pdf, etc.), how should the lua code then look like? The name can be written into the code, as long as I put decent comments in, I should be able to adjust it as needed. (File size shouldn't be a concern, the graphics are going to be 2-2.5 cm tall and once I've collected the appropriate graphics, I'll make sure the bitmaps are fit for this use. Besides, I'll be using a print shop and they get a lot worse than anything I can produce with ConTeXt...)
