Example photo from Canon Ixus 255 camera

SUMMARY


STEPS TO REPRODUCE
View a folder on the local hard drive containing JPG images copied directly from a camera's memory card. (Example image attached.)

OBSERVED RESULT
Images show as coloured squares in the image browser.
The image opens correctly in Gwenview when double-clicked.
The same image loaded and re-saved in GIMP shows correctly in the image browser. 


EXPECTED RESULT
JPG straight from the camera should appear as a thumbnail in the image browser.

Hi, Andy!
Thank you for your report!

I am just a user, not developer, but I found that bug highly critical for my usage scenarios and I'll try to add additional data from my installation to help developers to better understand the root of problem.

I download your file, add mine 2 files, place them into one folder and tried it on
```
Operating System: Manjaro Linux
KDE Plasma Version: 5.20.1
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1
Kernel Version: 5.8.16-2-MANJARO
OS Type: 64-bit
```
But in my case I see the thumbnail of the photo in browser mode in `gwenview` `20.08.2` (see attached snapshot).

What if it is fixed in current release? May be you can check it on current version of `KDE` and `gwenview` for example by update or to load (and update also) from from a latest LiveCD?

Still exists in Gwenview 21.12.3 on Kubuntu 22.04.
Problem only happens when "Low resource usage mode" is enabled in Gwenview's advanced settings.
