That's exactly what I did do :)
my-object: context [
img: make object! [
img-path: none
img-file: none
image: none
]
image-bank: make object! [
images: copy []
make-images: func [image-path /local c][
for c 1 16 1 [
append self/images make img [img-path: image-path img-file: join
image-path [c ".jpg"] image: load to-file self/img-file]
]
