I  file the code and could see is working.

SampleImageViewerMorph new on a Workspace
Or select the class in the Sustem Browser and alt - click for "more"
and then "sample instace"

Could be enhanced to read all the picts formats and not only jpg.

Hints:
Go to Utilities >> graphicsFileSuffixes.
Investigate "senders"
Have fun !
