This is not possible with PHP alone. You need Javascript to achieve this.

Why? You can make a function that uses SetTimeOut(15000) where you call the query in it making an infinite loop (ofcourse you must tell the function to echo the result or change the source of the image, which is easier done with JavaScript, yes.

There is one way to use only PHP, but you wouldn't be able to add or subtract images very easly. You could create an animated gif with all your images in it, set with 15 sec intervals between images. The animated gif would run continually, flipping thru the images.

How? SetTimeOut() is a Javascript function, and he doesn't want to refresh the page. How do you tell PHP to dynamically change an image without refreshing the page? Doesn't sound possible to me...

Hello,
Nico, I suppose you're right, I got mixed-up.
Job0107, it could be done dynamically, by getting all of the images from a database or xml, making a gif out of them, and then set them a 15 second interval.

I'm gonna go out on a limb here and try this:
(note: i'm not gonna test this code, i'm just throwing it out, play with it.)

PHP Code:

<?php
$imgcount = 0;
for($i=0; $i<15000; $i++){
    if($i=='14900'){
        $imgcount++;
        $i = 0;
    }
    if($imgcount=='15'){
        $imgcount=0;
    }
    
}

?>

Name your files (example: 1.jpg, 2.jpg --> 14.jpg)

then <?php echo "<img src=$imgcount.jpg>"; ?>

Now the problem lies in making the page refresh, the code i gave will make it change the file name every 15seconds ish, but it won't refresh the image display.
You'll need javascript for that. Read up on some ajax i guess.

Ok, so i probably didn't help much, but hey, i gave it a shot.

crasss. thanks for your reply. so if if i call a php script using [img] and [/img]
and inside that php there is javascript. Do you think the image will will change every few seconds ?
