Picture Gallery which rezises images

[Martin Brunner]

Hello!

I tested several picture galleries now but I didn't find anyone I like.

It should be very simple (just login and upload) but it should be able
to rezise pictures. You specify a value for the max height and max width
and depending if the hight or width is more the picture will be rezised
so that it fits into the gallery thumnails even if it was taken 90°
rotated.

Is there such a script available somewhere?

Not a gallery script, but my upload script does what you want

<?php

$filename="";
if (!empty($_FILES['userfile'])) {

if (is_uploaded_fi le($_FILES['userfile']['tmp_name'])) {

if ($_FILES['userfile']['size']>$max_size)
{ echo "The file is too big<br>\n"; exit; }

if($_FILES['userfile']['type']=="image/gif"){
$createfunction ="imagecreatefr omgif";}
else{$createfun ction="imagecre atefromjpeg";}

if (($_FILES['userfile']['type']=="image/gif") ||

($_FILES['userfile']['type']=="image/jpeg")) {

//check if file already uploaded
//if (file_exists($t humbpath ."s_".
$_FILES['userfile']['name'])) { echo "The file already exists<br>\n";
exit; }

//make a copy of original file
//$res = copy($_FILES['userfile']['tmp_name'], $path .
//$_FILES['userfile']['name']);

//create thumbnail image
$src_img = $createfunction ($_FILES['userfile']['tmp_name']);
$new_w = $thumbnail_widt h;

imagecopyresamp led($dst_img, $src_img, 0, 0, 0, 0, $new_w,

imagejpeg($dst_ img, $thumbpath

//create big image

$new_w = $main_width;
$new_h = imagesy($src_im g)/(imagesx($src_i mg)/$new_w);
