PHP Code:
<?php 
//
//this is to generate a random picture from a selected directory.
//the image files must follow the pattern: 1.jpg, 2.jpg, 3.jpg.
//

//
//Things to check and change.
//
$folder "../pic/"//path to the folder. (html style) (leave trailing slash)
$number 20//number of pictures in the folder

//
//The actual program itself.
//

//getting a random number from 1 to whatever user specified.
$random_number rand(120);

//changing the number into a string for use with the image path.
$random_number settype($random_number"string");

//generating the image path.
$image=$folder.$random_number.".jpg";

//displaying the image.
echo "<img src=\"$image\">";

//Volia :)

?>
The code is commented and pretty self explanatory, the only problem is that I am getting only one image (1.jpg) shown all the time.

Could someone tell me where I went wrong? Thanks
