Dear Nick and Helge: I would really like to see if every reference to an image in Gramps would be thumbnailed except for Media Reference... Media reference is the only place that I could needing to have the correct size of the image.... I think that it is important to have full size when you are trying to isolate media rectangle for specifying who is who in an image! Is there a way to get a list of image names and handles that are in the thumbnails directory? IIf there is, then it would be less work when you might need to get a thumnail image...
