If you want to stick with what you are familiar with, just to get the
project done, try looking up "imageSource" in the dictionary. With that, you
can change a character in a text field to be an image.

So make a background field with fixedLineheight turned off, centered text,
and a single character per line for each image you want on that card. You
can store the images anywhere in the stack and then use their ids like so:

set the imagesource of char 1 of fld 1 to 210096
set the imagesource of char 3 of fld 1 to 210067
set the imagesource of char 5 of fld 1 to 210097

(Note the use of odd number character indexes, so we don't replace the
returns.)

This way you have a simple scrolling list of images that's different on each
card. I use this method myself quite a bit to make lists of images. You can
have full control over selecting them and so forth, just as if they were
text... Which as far as LC is concerned, they are at this point.
