I have thousands of wallpapers and I like to rotate them on a specific time
limit. Since E17 uses the .edj
format for wallpaper, and the slideshow module only handles .edj files as well,
I wrote a little script to
rotate your wallpaper and store the image in a tmp folder so it won't interfere
with .e/e/backgrounds. You
can specify multiple directories in the script and it will randomly choose a
wallpaper from those directories.
I know the proper thing is to modify the slideshow module, but my C is so
rusty, I might get tetanus while
trying to modify the code.
