Fast way to mirror a number of images

[tumirnix]

Hello,
I've got a number of images from an iPhone (but as JPEG, not HEIC), which contain also "Selfies". Unfortunately the selfies are stored in a mirrored mode, I assume this is important for narcisstic people. But I would like to mirror it back (to be able to e.g. read the text on the T-shirt).

I know, that I can open every image in the editor mode an apply the vertical mirror. But this requires a bigger number of clicks (for each image).
Are there any faster options to apply this lossless operation? (Scripts, other mass operations).

Also a similar feature like the rotate-buttons on the overview page would be helpful.

Thanks in advance
Martin

Yes, use the Batch function. Create a new batch, click the plus button to add a command, select Flip Vertical. Select the photos you want to apply it to, then Run Batch. You can create a similar batch job for rotating.

Thanks roddyt for drawing my attetion to the Batch features, which I have not used so far.
Sadly, I was not successful with the batch (I tried a bit with and without an output folder, with and without the flag "Import output files").

But I found another way. In the Details I found the Orientation for the problematic images with the value "Normal Flipped". The following procedure seems to work

• Mark some of the images
• Set in Details the value from "Nomal Flipped" to "Normal"
• Click "OK"
• Re-create the thumbnails with Ctrl+Alt+T

Then the images are properly displayed in

• PhotoSupreme
• Windows Explorer
• XnView MP

Best regards
Martin
