    will handle 32,000 X 3 wallpapers.
    I just wrote a tiny C program to generate them. It works well with my randomizing and rotating scripts. Besides, I think that your method won't work. I'm not positive, but I think that all numeric variables are limited to 32K in bash. Don't quote me on that though.

    In case anyone wants it, here is my getrandom.c code:
    Code:
    #include <time.h>
    #include <stdlib.h>
    #include <stdio.h>
    
    /*
    ** With no parameter, just print the
    ** results of calling random() to stdout.
    **
    ** With a parameter, limit the maximum
    ** value printed to that parameter.
    */
    
    int main(int argc, char *argv[])
    {
            int i = 0;
            long int j = 0;
    
            /*
            ** Seed the PRNG with the current time.
            */
    
            srandom((unsigned int) time((time_t *) NULL));
    
            /*
            ** PRNG's generally return better results
            ** after they have been hit a few thousand
            ** times.  My needs aren't that strict, so
            ** I'll just hit it a thousand times. ;)
            */
    
            for (i = 0; i < 1000; i++)
                    j = random();
    
            /*
            ** Are we limiting the value?
            */
    
            if (argc == 2)
            {
                    printf("%ld", (j % atol(argv[1])) + 1);
            }
            else
            {
                    printf("%ld", j);
            }
    
            return 0;
    }

    You have to pull some tricks to optimize things so that the scripts will actually run in a reasonable amount of time.

    I did not check your scripts, but use wallpaper tray. This is a nice little program, that does everything I need (change randomly ...) and is easily downloadable with the synaptic package manager.

    I have to ask for those using gnome how sudden are the wallpaper changes.
    I remember i tried something similiar a few years ago in gnome but i didn't like how the transition from one wallpaper to the next was so sudden.
    I was looking for something that did smooth transitions from one wallpaper to the next like what happens in Mac desktops, has it progressed as far as that?

    A fellow user and I wrote a GUI program to do this. It works with Gnome's built in feature and it has a fading effect. It is released as a deb, so it can be installed with a couple clicks. It is GPL.
