Randome Image

Hello,
I want to display randome image on my index page, is there any script can display randome image??

Thanks

 

I made a simple script that displays a random image. You need to create a folder called "images" and place all the images you want to randomize in it.

<?
$images_dir = "images/";
$handle = opendir($images_dir);
$r = 0;



while ($file = readdir($handle)){
		if(!is_dir($file) && !is_link($file)){
			
				$image[] = $file; 
				$r++;
		}
	}

$i = mt_rand(0,$r-1);
echo "<img src=".$images_dir.$image[$i]." />";

?>

Code (markup):

 

Hey Man,
You doing great!!!

thanks alot
i'll test it now

thanks

 

Oops, I forgot to add the part that generates the random number .

I edited my previous post, and the script should work now.

 

$i = rand (0, $r-1);

PHP:

if there are 5 pictures in the array, your range would be 0 to 4 Oh, and mt_rand is 4 times faster than rand according to the manual.

 

Thanks, I fixed it. I also change rand() with mt_rand().

 

While we're on the subject, you should also initialize $image before the while loop, otherwise a user could manipulate it via the URL.

$image = array ();

PHP:

 

How would you get like 4 random images and make it clickable

 

or.

tablo.image
++++++++++++++++++
++id+++image_name+++
++1+++12345.jpg+++++
++2+++453.jpg+++++++
++4+++def.jpg+++++++

$query=mysql_query("select id,image_name from image order by rand() limit 0,1");
$img=mysql_result($query,0,'image_name');
echo "<img src='img/$img' border='0' />";

PHP:
