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 !
I got SampleImageLoader's loadImagesBelow working: the problem was that it was trying to match files ending with .jpg or .jpeg, but my files had .JPG.
I still am having problems with the package though. It appears that the SampleImageLoader is not getting hooked up with the Model correctly.
Are you using 3.9?
