Check the Show videos checkbox to allow Gwenview to show videos among the images.
- Background color
Move the slider to change the color of the gray background in Browse and View mode from black (the leftmost position) to white (the rightmost position).
- JPEG save quality
JPEG save/compression quality setting, which can be temporarily overridden in the Save As dialog when saving a file as a JPEG. When saving an existing JPEG file with a new name or after performing a non-lossy edit (e.g. rotation, which only changes the EXIF rotation tag), the appearance of the file is not changed because no actual image manipulation is done.
- Thumbnail actions
Whether the thumbnail action buttons should be shown as overlays above image thumbnails.
All buttons — Show all buttons
Show selection button only — Show select/unselect button only
None — Do not show any thumbnail button
