Makes a montage with snapshots of your images and saves it in their directory.
When you middle click on this preview montage with the Multi tool, it will open the selected image (everything needs to be on the same directory)
First : open all the images of one directory or just the ones you want, (it can be virtual stacks).
Adjust the display you want (slice, contrast, LUTs..) because the snapshots will show the current views.
Then click on the tool to create the montage.
Note : The Montage title needs to contain precisely “Preview Opener” to work but you can add text before or after.
