Hi Sannyasin,
I just woke up and I’m not sure I am
following what you are trying to do at all,
except that you are wanting images to
be preloaded into your stack.
Are you doing Import As Control —> Image File
That should load preload the image into
memory into your stack so you don’t
experience a delay.
I hope that helps.
If I’m not following things, then never-mind.
I’ll look at this again when I am more awake.
Cheers,
Rick
