Hi!

Im using an random image script which works fine but that I want to edit a bit. I have edited it a bit so when you click on a image you get a fullsize in a popup. The problem is that the image in the popup is also random and not always a bigger copy of the thumbnail, the smaller one you clicked on as I want:

see it live here, and I think you will understand what I want to achieve:
see it here

the code Im using is:
randim.php

<?php
/* The default folder with images */
$settings['img_folder'] = 'bildermini/';

/* File types (extensions) to display */
$settings['img_ext'] = array('.jpg','.gif','.png');

/*
   How to display the images?
   0 = print just the image path (for includes), like: images/test.jpg
   1 = redirect to the image, when using: <img src="randim.php" />
*/
$settings['display_type'] = 1;

/* Allow on-the-fly settings override? 0 = NO, 1 = YES */
$settings['allow_otf'] = 1;

/*******************************************************************************

/* Override type? */
if ($settings['allow_otf'] && isset($_GET['type']))
{
	$type = intval($_GET['type']);
}
else
{
	$type = $settings['display_type'];
}

/* Override images folder? */
if ($settings['allow_otf'] && isset($_GET['folder']))
{
	$folder = htmlspecialchars(trim($_GET['folder']));
    if (!is_dir($folder))
    {
    	$folder = $settings['img_folder'];
    }
}
else
{
	$folder = $settings['img_folder'];
}

/* Make sure images fodler ends with an '/' */
if (substr($folder,-1) != '/')
{
	$folder.='/';
}

/* Get a list of all the image files */
$flist = array();
foreach($settings['img_ext'] as $ext)
{
    $tmp = glob($folder.'*'.$ext);
    if (is_array($tmp))
    {
    	$flist = array_merge($flist,$tmp);
    }
}

/* If we have any images choose a random one, otherwise select the "noimg.gif" image */
if (count($flist))
{
	$src = $flist[array_rand($flist)];
}
else
{
	$src = 'noimg.gif';
}

/* Output the image according to the selected type */
if ($type)
{
	header('Location:'.$src);
    exit();
}
else
{
	echo $src;
}
?>

and for calling 3 random images:
test.php

<ol>
click for bigger image:
<li>
<a class="fancy" rel="fancy" href="<?php $_GET['type']=0; $_GET['folder']='bilderstora'; include 'randim.php'; ?>"><img border='0' src="<?php $_GET['type']=0; $_GET['folder']='bildermini'; include 'randim.php'; ?>"></a></p>
</li>

<li>
<a class="fancy" rel="fancy" href="<?php $_GET['type']=0; $_GET['folder']='bilderstora'; include 'randim.php'; ?>"><img border='0' src="<?php $_GET['type']=0; $_GET['folder']='bildermini'; include 'randim.php'; ?>"></a></p>
</li>

<li>
<a class="fancy" rel="fancy" href="<?php $_GET['type']=0; $_GET['folder']='bilderstora'; include 'randim.php'; ?>"><img border='0' src="<?php $_GET['type']=0; $_GET['folder']='bildermini'; include 'randim.php'; ?>"></a></p>
</li>
</ol>

how do I edit the code so I get the same image on the link as it is on the thumbnail?

the images are stored in:
bildermini/ (thumbnails)
bilderstora/ (big image)

thanks for your help!

Alter randim.php slightly. Instead of including it twice, include it once, at the start of the link, and instead of having it echo the URL to the selected image, put it in a variable (or two, one mini, one stora). Then echo that variable within the href attribute's value.

<?php $_GET['type']=0; include 'randim.php' ?><a ... href="<?php echo $bilderstora_url ?>"><img src="<?php echo $bildermini_url ?>" /></a>

On an aside, you have an unusual setup, here; I'm guessing it's been adapted from an another setup where "type" and "folder" were supplied in the URL. The use of $_GET['folder'] to specify which folder is requested will be a problem.

What you could do instead is pick which random images to display in test.php, and then that page will be able to work out what their URLs are and put them into the links directly.
