How do I import/read images and their ID from a separate folder to change the icon of a button?

Thanks for the info!
It's not quite working because it needs to happen 'invisible' so
'answer file'  is not what I need.
And then there is the random function as well.

Do you think it is possible to use "put the files into fld "pictures"
and then pick one at random?

greetings,

William

So you could have a button that references an id of an existing image object, which in turn references an image on your hard disk. I suggest to look up the fileName dictionary entry, barring that, here's an example (untested):
