Nautilus opens images with GIMP, not image viewer

[svref]

By default, I think Nautilus should open .jpg files with an image viewer, but on my system it opens them with slow-starting, image-hard-to-see-because-of-window-cluttering GIMP.

I thought this would be easy to fix, just use Nautilus's Edit > Preferences > Media > Images: Open Image Viewer. But that has no apparent effect on the click-behavior of Nautilus!

Help!

Right click an image and go to Properties>Open With and select what you want. You may have to do that with each type of image file. (png, jpg, etc)

Nautilus doesn't store the result of "Open With" persistantly. I "Open With" whatever, and then go back and click the image, it opens it again in the GIMP.
The above applied to Right click > Open With. Your advice is correct. Thank you.
