I use the Micro Photo Gallery the script finds all .jpg files and creates thumbnails if there isn't one and links the thumbnail with the jpg file.

I will use this script on a site, and I don't want to upload the same gallery on the other site, I just want the script to read from the folder of my first site the files. The original script only reads from the folder that is in.

Here is the script:

<?php

    // Get the original geometry and calculate scales 
    list($width, $height) = getimagesize($originalImage); 
    $xscale=$width/$toWidth; 
    $yscale=$height/$toHeight; 
    
    // Recalculate new size with default ratio 
    if ($yscale>$xscale){ 
        $new_width = round($width * (1/$yscale)); 
        $new_height = round($height * (1/$yscale)); 
    } 
    else { 
        $new_width = round($width * (1/$xscale)); 
        $new_height = round($height * (1/$xscale)); 
    } 
    // Resize the original image 
    $imageResized = imagecreatetruecolor($new_width, $new_height); 
    $imageTmp     = imagecreatefromjpeg ($originalImage); 
    imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height); 
 
    return $imageResized; 
}

I don't think that you can do what you want with this script.
It's based on a mechanism that scan the current directory structure.

URL access to a file is a completely different mechanism and cannot be implemented transparently at that level.
What you could do, is map a network drive through a VPN, and use that network drive as a source.

But in the end, I strongly discourage you of doing that.
It's just not worth the troubles...

Is your site on your same server and do you have access to that site's directory over your FTP connection?

My new website isn't on the same server as the old

As long as the directory can be accessed through FTP without a password it can be done. http://us3.php.net/function.opendir so in other words if you can connect to ftp://your.domain.com/images without using a password then you can use this script, otherwise it's not possible.

To have access throw ftp I have to insert my password. This script doesn't do the job, I was thinking of a script that searches the page for the thumbnails and the link to that image

<a href="http://domain.com/images/path/1.jpg"> 
<img src="http://domain.com/images/path/1_th.jpg"></a>

the script searches the page finds the link and puts in my page.

Another problem is the link, the link lucks like images/path/1.jpg the script will have to change it to "http://domain.com/images/path/1.jpg"
