Well, you didn't post all of your code, but the following should work:

[code=php:0]
<?php
$imageArr = array();
$imageArr[] = "/pics/fish.jpg";
$imageArr[] = "/pics/robo.jpg";
?>
[/code]
There is no need to explicitly assign numeric keys.

Oh yeah, and note that you aren't actually storing the images in array, but the string location.

thanks, I'll try. I want to display pictures in random way, that's why I assigned the numeric keys....

It doesn't work, here is the code:

<?
//array to hold the pictures
$imageArr= array();
$imageArr[1] = "/pics/fish.jpg";
$imageArr[2] = "/pics/robo.jpg";

//randomization
$imageShow = rand(1, count ($imageArr));?>

//to show the pictures in random way
<? echo $imageArr[$imageShow]; ?>

[willfitch]

Use array_rand().

[code=php:0]
<?php
//array to hold the pictures
$imageArr= array();
$imageArr[1] = "/pics/fish.jpg";
$imageArr[2] = "/pics/robo.jpg";
$rand_keys = array_rand($input);
echo $imageArr[$rand_keys[0]];
?>
[/code]
That will randomize your array.

no:( [color=red]Warning: array_rand(): First argument has to be an array in /users/3d_cn/html/test/index.php on line 16[/color]

I'm sorry.  I had a different var name:
[code=php:0]
<?php
//array to hold the pictures
$imageArr= array();
$imageArr[1] = "/pics/fish.jpg";
$imageArr[2] = "/pics/robo.jpg";
$rand_keys = array_rand($imageArr);
echo $imageArr[$rand_keys[0]];
?>
[/code]

[Gruzin]

on, it doesn't display any pictures, Should I try it another way? thanks anyway:)

[willfitch]

Come on now Gruzin! 
[code=php:0]
<?php
//array to hold the pictures
$imageArr= array();
$imageArr[1] = "/pics/fish.jpg";
$imageArr[2] = "/pics/robo.jpg";
$rand_keys = array_rand($imageArr);
echo '<img src="'.$imageArr[$rand_keys].'" />';
?>
[/code]

[Gruzin]

thanks, man think it will work:)

[willfitch]

LOL No prob.  Please don't think that I was being mean; I was only playing!

[Gruzin]

ye that's okay:) It doesn't display the picture corectly:( here is my directory:
/html/test/pics

I don't know why...

[willfitch]

When using abs paths, you need to specify from the web root.  If your web root is /html then do this:

[code=php:0]
<?php
//array to hold the pictures
$imageArr= array();
$imageArr[1] = "/test/pics/fish.jpg";
$imageArr[2] = "/test/pics/robo.jpg";
$rand_keys = array_rand($imageArr);
echo '<img src="'.$imageArr[$rand_keys].'" />';
?>
[/code]
