how to select a value randomly

how to select a value randomly
on my desktop i am using the kde rotating desktop image option. this rotates images randomly every half hour. now, i would like to write an html file which will have an inline frame with some text, maybe system messages, or my friends live journal thati read alot, or unix.com! however, i dont want to give up my rotating desktop images.
my proposal:
define one variable that would equal a value from a given set of OTHER variables. say i have
String picture;
then i have
String picture1=picture1location;
String picture2=picture2location;
and so on, i have maybe 50 images.
how can i make the first string 'picture' randomly equal the value of picture1 or picture2 or picture3 etc etc.?
further more, after i sort that out, how can i then set the value of 'picture' to the html file's background image?
at first i was gonna use SSIs, but i realized that there is no server to interpret the SSIs because the file is going to reside on my desktop in the same directory as all of my image files. i think javascript would be good for this, or PHP?
ill have the page refresh every 30 minutes.
well if anyone can help thatd be great.
all i really need is a way to change a background image in an html page randomly at a given interval.
thanks again!

What I have are two text files that I need to shuffle randomly, but I need the two files to be randomly shuffled the same way. I have heard of shuf but I do not know how to use it for two files. Maybe there is also an easy/simple awk command I do not know about that could handle this problem.
