Thanks! Never heard of this one, trying it now ...

I use Mirage.

A lot display, but that is not my favorite, it is just quick.

My favorite image viewer is quite dumbly the one I programmed myself years ago. As regards going forward and backward in a collection of photos or icons, it is just as good as anything else. But maybe I had never understood the functions of other programs. With this one I believe I know about everything it can do and even how I will use it...

I'm disappointed in nomacs, when I rotate and wish to save the new orientation then it wants to recompress the picture instead of updating metadata only.

I like using nomacs, too. Unfortunately, I don't see it in the Bullseye (testing) repos. Maybe I can install it in Bullseye anyway? On a few installations where I did in-place upgrades from Buster to Bullseye, nomacs was not removed and is still working normally, as far as I can tell.

Geeqie is another one I've been using. I've used Mirage in the past -- switched from that to nomacs.

I installed from SID to get it in Bullseye for now. Once it goes stable...I'll see if I want to use something else or not.

For ease of use, I go with Gwenview (KDE). Easy on, easy off. Quick loading. It does a couple of things very well: Crop and Resize. Like I said, no hassles and good results.

I use Nomacs. It is best Image viewer in my opinion.
You can even view RAW images with no problem.

But which viewer allows for rotating and saving the new orientation without recoding the image?

There are many faulty assumptions going on here.

1. I use a different tool for viewing and editing images. The two functions are very different, and I use the tool that is best for what I am doing in the moment.

2. In the same line, my viewing tools depends upon what kind and format of images I am viewing, so I use different viewers for different collections of images.

Within the Linux/BSD community we have more tools than any other OS environment in history. Why tie yourself to one tool for one kind of job, even when it may not be the optimum choice? Explore your universe!

What about being practical. I download new pictures from my camera, now I'm viewing them. Some I want to delete, some I want to rotate. Is it too much for a viewer? I have to fire up another application for this? I remember in past I had such a viewer, but then it disappeared, maybe some Python upgrade was to blame. Now I even don't remember what it was, Mirage perhaps ...

Any recent camera is likely to be setting an Orientation Exif tag, which should avoid the need for you to do this manually.

Confirm whether the photos have that tag, and if so raise a bug report in any software not respecting it.


There's a reason "View, Sort, and Manage" is a single category at https://pixls.us/software/

I have Mirage at present (Fedora 34)

Yes, it is in a Gentoo overlay - broken, removed from portage because of unsupported Python version. I don't know what happened to my camera, it used to get the orientation right, but not any more, so I have to set it manually. It think Wife dropped it, perhaps the sensor broke. Maybe one day I'll see what can be done to start using it again.

Edit: Got it working with python-3.8! Indeed, it saves orientation without recoding the picture.

Thank you RockDoctor!

That is exactly why I wrote my own program around 2004. During my holidays and in my hotel room. C++/Qt sourcecode, only. Sorry:

This is now old software. But I still use it. Rarely, as I do not keep photos these days.
