On one slide, show different images, loaded from a list

@Susan:

Thanks for the link towards the script. I knew the website, but as you
said, it takes a lot of time (sometimes) to find something actually
useful. I have been going through some scripts though in the hope to
get some clues, ideas and maybe solutions, but I didn't try your
script. I will have a look into it once my head will be fresh again
(in other words: tomorrow or this weekend). :-)

Thanks a lot!
