Need Help with Image Uploads and Watermarks

[irishpeck]

Ok so we have a new classifieds website called www.flog-it.ie. On this website we allow people to upload images to the website. These images are stored in our database. How do we setup so that when someone uploads an image it automatically applys a transparent png or gif as a watermark to each image? Below i have added the code for putting the images into the database imgs.php.

 

***imgs.php***

 

<?php

require_once("config.inc.php");
require_once("pager.cls.php");

// Pager
$page = $_GET['page'] ? $_GET['page'] : 1;
$offset = ($page-1) * $images_per_page;

if ($sef_urls && !$xsearchmode)
{
$urlformat = "{$vbasedir}$xcityid/images/".($xposterenc?"$xposterenc/":"")."page{@PAGE}.html";
}
else
{
$urlformat = "?";
$tmp = $_GET;
unset($tmp['page'], $tmp['msg']);
foreach ($tmp as $k=>$v) $urlformat .= "$k=$v&";
$urlformat .= "page={@PAGE}&cityid=$xcityid&lang=$xlang";
}

// The link to see all images
if ($sef_urls)
{
$allimgslink = "{$vbasedir}$xcityid/images/";
}
else
{
$allimgslink = "?view=imgs&cityid=$xcityid&lang=$xlang";
}

// View conditions
if($xposterenc) $whereplus = "AND MD5(CONCAT('IMG', '$encryptposter_sep', a.postername, '$encryptposter_sep', a.posteremail)) = '$xposterenc'";

$whereplus .= " $loc_condn_img";

?>

Would you be able to help me with my code though? I dont know where to enter the code in the relative file.

 

[RussellReal]

click the link that the function name is, it will take you to php.net and they explain all the parameters

[irishpeck]

Yeah i went there but im not a php programmer i only know the basics, i dont know how to compile the code i need or where it should go in the code ive given!

[RussellReal]

there is no INSERT query, in that whole file, this can't be the correct file to help you with, but to be completely honest, this is more of a script request than help, as you personally aren't a PHP developer, and the admins are awake atm for whatever reason and will most likely move the topic to the freelance forum
