Seems like everyone may be missing what Carolyn is asking, if you want
associated text with image that randomly selected, what you need is some
sort of database. You do not need a real database a flat file table
would do. How you implement it depends on whether client-side JavaScript:
function Snapshot(src,text){
this.src=src;
this.text=text;
}
var snapshots=new Array;
var i=0;
snapshots[i++]=new Snapshot('someImg.jpg','My text about some image.');
snapshots[i++]=new Snapshot('anotherImg.jpg','Text about another.');
....
make a random function that picks a number between 0 and
(snapshots.length-1)
then another function to write in associated image src and text
document.write('<img src="' + snapshots[randomNum].src + '">');
document.write('<p>' + snapshots[randomNum].text+ '</p>');
Perl, or PHP or other server-side scripting (which would be a far better
solution)
create a text flat-file database with text editor say, 'snapshot.txt':
#image field [tab separator] text field
someImg.jpg My text about some image.
anotherImg.jpg Text about another.
....
Have you script read the file 'snapshot.txt' into an array and like the
JavaScript pick a random number then build page or the results (Perl
show)...
my $lastRec = $#snapshots;
my $randomNum = RandomFunc($lastRec);
my ($imgSrc, $imgText) = split("\t", $snapshots[$randomNum]);
then build page as required...have fun!

Take care,
