Bug ID: 499241
Summary: Dolphin jpeg preview is reversed
Classification: Applications
Product: dolphin
Version: 24.12.1
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org

Target Milestone: ---
Hi,
I realized that jpgs in a folder have no preview for jpg files. Pngs, webm and
everything else has jpg previews, even better in other folders jpg previews
show up. But! When I turned off previews for dolphin (Settings->Dolphin
settings->Preview->Jpeg, untick, click Apply), the thumbnails showed! When I
turn it back off, the thumbnail disapper. If I move the image between that
folder and other folders, the experience is the same. The images I experience
it with are downloaded from bonjourmadame.fr (NSFW), so it may be the images
from that site (but the webm, png files from the same site show no trouble). I
experienced it with a single folder where I collect them, that folder is synced
to Nextcloud with the official app, but the connection may be the source of the
images.
So in summary: jpg files from that site react to "Show JPEG thumbnails"
reversed compared to what the tick suggest in dolphin. Example image: the one
from 2025-01-28 (the page uses /page/n numbering, don't see permalink option)
Hope you can look into it!
BR,
Gergely
