Image thumbnails of the .webp fileformat do not display inside Thunar and on the desktop. It's possible that this is linked to Tumbler, which is used by Thunar/Xfce.
Created attachment 6641 [PATCH] Add Webp thumbnailing capabilities to tumbler Attached is a patch that adds webp thumbnailing capability to tumbler for thunar and xfdesktop. Requirements are: - gdk-pixbuf2 2.2.2 - libwebp 4.0.3 This patch has only been tested on two systems and needs further testing. (Note: this bug report should be filed under tumbler.)
moved to tumbler
Since tumbler version 0.2.0 and the re-introduction of the desktop thumbnailer plugin, this patch is no longer necessary. Simply create a /usr/share/thumbnailers/webp.thumbnailer file with the following content: [Thumbnailer Entry] Version=1.0 Encoding=UTF-8 Type=X-Thumbnailer Name=webp Thumbnailer MimeType=image/webp; Exec=/usr/bin/convert -thumbnail %s %i %o Restart tumblerd or log out and back in again for it to take effect. Note: make sure there is an image/webp mimetype defined in your system.
