Thumbnails Script

naissa

The thumbnails script that I use for my gallery doesn't work.
To create automatic thumbnails I use

<?php
$image = $_GET['image'] ; 
$newwidth = $_GET['newwidth'];
$newheight = $_GET['newheight'];
$height = $_GET['height'];
$width = $_GET['width'];
if (ereg('png$',$_GET[image])) {    $src = imagecreatefrompng($image); } 
if (ereg('jpg$',$_GET[image])) {    $src = imagecreatefromjpeg($image); } 
if (ereg('gif$',$_GET[image])) {    $src = imagecreatefromgif($image); } 
$im = imagecreatetruecolor($newwidth,$newheight);  

imagecopyresampled($im,$src,0,0,0,0,$newwidth,$newheight,$width,$height); 
imagejpeg($im, '',85);
imagedestroy($im); 

?>

but the thumbnail is not displayed. Can u help me please? Thanks

you are not saving the image to the disk, or sending it to the browser with the appropriate headers.

no I don't want to save it to the disk I just want thumbnails to be created on a fly. It worked before but now that php upgraded it doesn't anymore. Is there a way to do this without GD

i dont see why people dont just make the images certain size in html. just make a Iframe then make xml database with all the image paths. then make a xsl template that outputs the images with xsl:attributes to srcs from the xml database in a loop, xsl:for-each would be they way i would do it

because then the user still has to download the large image and if there's a bunch of them on a page that can be a significant download time. I don't know why people don't do a little reading before making stupid comments.

well I was only trying to help. That didnt cross my mind 🙁. I would say the best way of doing this would to have when u upload images to the gallery make a tumbnail too. have some sort of file naming system. But hmm, I have always found GD to be a pain. (easy to glitch) hmmm.

Does it give you any errors when u run it?

I know you were trying to help. I would actually recomend the same thing as this, because of server load with on the fly thumbnails. Here is how I would do it:
