Transforming JPEG Images into Morphs

I tried this in Pharo 1.4 one-click but got an MNU: 'reset'. It does work, however, in Pharo 3 one-click.

It has been a very long time that I did anything in 1.4 ;-)

The reason is that my code snippet is using the newer FileSystem API, which was probably not ready back then. The older variant not using the newer API is:

FileStream
fileNamed: '/Users/Sven/Desktop/test.jpg’
do: [ :in | (JPEGReadWriter on: in) nextImage asMorph openInWindow ].

But I did not test this.
