In Plasma 5.24, Dolphin could be set to ignore EXIF thumbnails embedded in JPEG files. This changed at some point, not sure when, but now you can no longer do that, so Dolphin will always show EXIF thumbnails when available. This can be a problem because images saved online can have low quality or flipped EXIF thumbnails.
