multiple random image display

[dotcomtim]

I am looking to know if there is away to take my random image script to multiple images with using a database..

I currently have a directory of 20 or so images and would like to randomly display four of them on my page without any of them being duplicates > they all have to be unique.

This is what I am currently using for one image

$imgDirectory = opendir("images/random_insert");
$imgArray = array();
while ($file = readdir($imgDirectory))
{
if($file != "." && $file != "..")
{
array_push($imgArray,$file);
}
}
closedir($imgDirectory);

mt_srand((double)microtime() * 1000000);
$randval = mt_rand(0,sizeof($imgArray)-1);
$getEd = "<img src=\"/images/random_insert/".$imgArray[$randval]."\" width=\"150\" height=\"440\" border=\"0\" alt=\"\">";

You say "with using a database..". You can store the names in a table in a database, then do a query such as:

SELECT filename FROM table ORDER BY RAND() LIMIT 4

That would give you 4 random, but unique, file names to display....

I been working on this for to long that I didn't read my post.. Sorry that to say without using a database...

Currently I am playing with an array with the image names... Not as effective then what I was looking for but I am not getting errors or duplicates but it still is automated as I wanted also..

Consider using array_rand or a simple shuffle ... and use the first four.
