It might be okay when it uses something other than Windows picture and fax viewer to open the images. Even using the default file association program used for the file extension would be better. I see from the development notes that a configurable viewer is planned. That can't come soon enough as the current program I just could not be bothered using.

This review is for a previous version of the add-on (0.2.5.1). 

Voila
