Please verify if this crash happens in your platform
while importing a JPG image into a stack created
in LC8:
Write in the message box:

After the new stack appears, write in the message box:
create image
Now, using the Pointer Tool, select the (invisible) image
in the center of the stack and in the Menu Object,
select Object Properties...
In the Object Properties palette, click
the Source button [...] and select a JPG image
LiveCode 8 hangs and become unresponsive.
PNG and Animated GIF imports fine, without problems
and (surprise) Animated GIF could be scaled (up and down) nicely!
