Hi,
When using a buffer with about 5000 images,
image-dired-mouse-toggle-mark takes about 1-2 seconds for one image.
This is not a big problem. But when using this function on a region with
about 200 images, then you need to wait several minutes for completion.
That's because image-dired-thumb-update-marks is called in the macro
image-dired--on-file-in-dired-buffer and therefore unnecessarily for
each image in the region.
What could be a good way to avoid the repeated calls to
image-dired-thumb-update-marks please?
TIA for any help,
--
Peter

This works, but I don't know if it's not too hackish:

Thanks for the updated patch, as well as the very good bug report that
indicated clearly not just how to reproduce it but also the root cause.
However, I think we should avoid mocking out that function, so I
attempted to solve this in a more clean way on master. Could you please
rebuild latest master, and verify that the bug is fixed for you too?
