Image Scaling Problem

You use the imageData technique when you want to reduce the dimensions AND
the filesize of an image (could also be called a "lossy" process because
you lose data by using this method).
For example, say an 800x600 image runs 2MB. If you reduce the dimensions
of the image and lock it, the image still occupies 2MB of memory, and can
be restored to its original dimensions when unlocked.
The imageData technique is similar to scaling an image in something like
Photoshop or GIMP: you are removing imageData, the image will only occupy
a few hundred K or less, and cannot be restored to its original size.

>> Hello List,
>> I just imported a 500x500px image as control into a stack, resized it
>> using its handles to about 100 x 100 px, saved the stack and closed
>> After restarting livecode and reopening the stack the size of the image
>> was again 500 x 500px.
>> What may I do to make the scaling permanent?
