Image scaling:  when working on a magazine article image frames often have similar scaling for the images within them, and image frames can be cloned and copied  - however, every time a new image is inserted into a frame, it defaults to 100% instead of the inherited frame aspect - which is how I would expect it to happen.  This then necessitates lots of clicks to reset the image scaling to the one it was copied from.

Otherwise, it's a matter of looking at the Scaling of the image in Properties before you load a new image.

I've written a script, retainscaling.py that manages this issue. It's actually quite simple. After some error checking to make sure there is only one frame and it's an image frame, its scaling is obtained.
A file dialog opens to choose a new image file. The file is loaded and the scaling set to the previous settings.

USAGE
You must have a single image frame selected. Its scaling is noted.
A file dialog opens to load a new image. New image is loaded, scaling set to
same as previous image.
