When I tried to import a picture earlier I accidentally set the S-note picture import preference to Gallery. Before that I was given the choice to import from Astro etc. .
I tried to delete all s-note data/cache in the preferences, but I was unable to reset the picture import to the non default value. (It didn't even delete the Documents on the device, they were back after a reboot).
The reset to default values button in the Task manager is greyed out.
