I have a watermarking script, some of you might have seen before from one of my previous questions:
<?php
$imagesource = $_GET['path'];
$filetype = substr($imagesource,strlen($imagesource)-4,4);
$filetype = strtolower($filetype);
if($filetype == ".gif") $image = @imagecreatefromgif($imagesource);
if($filetype == ".jpg") $image = @imagecreatefromjpeg($imagesource);
if($filetype == ".png") $image = @imagecreatefrompng($imagesource);
if (!$image) die();
$watermark = @imagecreatefrompng('watermark_'.(imagesx($image) <= 1100 ? "port" : "lans").'.png');
$imagewidth = imagesx($image);
$imageheight = imagesy($image);
$watermarkwidth = imagesx($watermark);
$watermarkheight = imagesy($watermark);
$startwidth = (($imagewidth - $watermarkwidth)/2);
$startheight = (($imageheight - $watermarkheight)/2);
imagecopy($image, $watermark, $startwidth, $startheight, 0, 0, $watermarkwidth,
$watermarkheight);
imagejpeg($image);
imagedestroy($image);
imagedestroy($watermark);
?>
The script works fine, but when my client uploads a picture which is over 2000px X 2000px (or smething around there) the script outputs nothing not even an error. But, when I reduce it to 1100px X 800px for example this script outputs and displays the image. Is there any reason for this?
Is there anyway to either diagnose what is causing this and hence find a solution or to automatically re-size the image on upload?
This is the upload script I currently have:
<?php
if (($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg"))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
if (file_exists("uploads/" . $_FILES["file"]["name"]))
{
echo "<h3>".$_FILES["file"]["name"] . " already exists. </h3>";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"uploads/" . $_FILES["file"]["name"]);
echo "Stored in: " . "uploads/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "<h3>Invalid file</h3>";
}
?>
Thanks to Josh I have found this direct solution which I have integrated. Thanks again!
