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?

> Not exactly like that, but you can create image objects that only reference an stored image somewhere, by setting it's fileName. 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):
