Need a Linux solution for looped slideshow from pictures in some folder. Pictures may be deleted and added, so it's a bonus if it doesn't stop/crash if currently shown picture is deleted.
This is going to sound crazy, but it works (better than I expected even) and is not that hard to setup. The idea is to make your viewing program look at a single file and then have a command line process that copies each of your files in your directory to that file you view. I tested this with Geeqie and gthumb and it actually works pretty well. gthumb even can handle the image being updated every second and both supported the name of the file type being different from the actual file type (jpg, png, gif, etc).
So here is what you do:
When you are ready to stop the slideshow, you can press Ctrl-C in the terminal window.
If you use Gnome desktop, then you can use its official image viewer program for slide shows:
With Eog pictures can be removed or added during the slide show. Actually, if you add picture during the slide show, it will be automatically included.
