Steps to Reproduce: 1. Prepare a folder where all images don't have file extensions (image instead of image.jpg) 2. Right click on desktop and select "<desktop_name> Settings" 3. From Wallpaper dropdown select Slideshow 4. Click Add Folder button 5. Select folder from step 1 6. Click Apply or OK Actual Results: Only images with file extensions are shown. If no image has file extension then I only get a black background color on desktop. Expected Results: Slideshow plugin should be showing images even if they don't have file name extension.
BackgroundFinder only checks file extensions for speed apparently
Suffix is checked instead of metadata to speed up the loading.
