Sounds familiar now. I am notarizing build 3 to post in a new minutes. In this version, new files are not create to "not save thumbnails." While that is best for keeping good thumbnails, there is one good reason toe save thumbnails. If you save thumbnails of all images in your file, you can take just the .gedpkg file to a new computer and still be able to view images. You do not need to copy all the multimedia files to the new computer as well.
To be sure you save all the thumbnails, a good process is:
1. Open "Options" pane of the "Multimedia Options" panels
2. Choose a size in pixels (depending on quality of images you want)
3. Click "Create All" button (if you changed the size, click "Delete All" first and then "Create All")
4. Check box to include thumbnails in the file
5. Save the file
This new saved version can travel and have all images. Of course you will not be able to edit multimedia on the other computer, but you can see them all.
