I've tried setting image-dired-thumb-size (and/or image-dired-thumb-height image-dired-thumb-width) and it has no effect. I've set it globally in .emacs and in various mode-hooks, all to no avail. The default value is 100 and I change it to 256 and the thumbnails are still 100. Inquiring the variables says they are 256.

These variables seem to have no effect. Is there a way to make this work?

I found the problem. It appeared to be broken (changing values had no effect) because image-dired caches its thumbnails in ~/.emacs.d/image-dired/. Clearing the cache makes the changes effective.

    Just a note for people who might be struggling with the issue of thumb sizes: **it's not sufficient** to just change `image-dired-thumb-size`, you **also have to change** `image-dired-thumb-height` and `image-dired-thumb-width`! – heinwol Jun 26 '21 at 15:53
