Cool. That heavily commented SampleImageViewerMorph>>initialize is
especially useful

I am not sure, but every time I hit enter in the dir box, or
click the main panel, I get a debug window. What Squeak version
is this made for? I am using 3.8. A quick question: is the
correct way to run this program:
SampleImageViewerMorph new openInWorld

We have not considered a code repository, but this morph is
quite simple, and may be useful in a tutorial. I might
incorporate it into my beginner's tutorial:
