Hi Gabriel,
Does anybody have a clue of what is going on?

ImageJ 1.x opens sample images differently if they are cached or not. One
of these pathways uses SCIFIO (when the image is cached) and one uses
ImageJ 1.x (if it's not cached)... I believe because we didn't want to be
overly aggressive in inserting SCIFIO into every single ImageJ 1.x
operation.. but perhaps this is too confusing in respect to cached images,
or at least should be documented in the WELCOME.md.
If you disable SCIFIO (Edit > Options > ImageJ2, uncheck the "Use
SCIFIO...") both cached and uncached sample images should open the same way.
Also, when you have an image open, if you run Image > Show Info you can
easily tell if your data was opened with SCIFIO or not.
Let me know if you have any other questions.
Thanks!
- Mark
