about pbimageviewer on Inkpad with fw5.

use the fwv5 zip file of the 1st post.
the app file must be stored both in /applications ans /system/bin folders.
the updated extensions.cfg file must be stored in /system/profiles/<profile-name>/config folder. The default <profile-name> is simply default.
the 840.cfg file must be stored in /system/share/pbiv folder.
then you can read cbr, cbz, ... both in landscape or portrait mode.
using applications tab, you can browse your pictures folders. I recommand using the NextPage and PreviousPage buttons to navigate both in folders and pictures.
Thank you rkomar.

Enjoy
