Hi all!
I have a short php gallery script that creates and displays thumbs.
I'm trying to include the thumbs on a cms page, but they don't show.
I've tried just about everything I can think of.
Does any one know why these thumbs won't show?
I have a feeling it's because the gallery is not in the same directory as the cms...but I'm not sure how to correct.
Here's the code:
<?php
$columns = 5;
$thmb_width = 120;
$thmb_height = 80;
function resizeImage($originalImage,$toWidth,$toHeight){
// 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;
}
function generateThumbnails(){
global $thmb_width,$thmb_height;
// Open the actual directory
if ($handle = opendir(".")) {
// Read all file from the actual directory
while ($file = readdir($handle)) {
// Check whether tha actual item is a valid file
if (is_file($file)){
// Check whether the actual image is a thumbnail
if (strpos($file,'_th.jpg')){
$isThumb = true;
} else {
$isThumb = false;
}
if (!$isThumb) {
// Process the file string
$dirName = substr($file,0,strpos($file,basename($file)));
if (strlen($dirName) < 1) $dirName = '.';
$fileName = basename($file);
$fileMain = substr($fileName,0,strrpos($fileName,'.'));
$extName = substr($fileName,strrpos($fileName,'.'),
strlen($fileName)-strrpos($fileName,'.'));
// Check if the actual file is a jpeg image
if (($extName == '.jpg') || ($extName == '.jpeg')){
$thmbFile = $dirName.'/'.$fileMain.'_th.jpg';
// If a thumbnail dosn't exists tahn create a new one
if (!file_exists($thmbFile)){
imagejpeg(resizeImage($file,$thmb_width,$thmb_height)
,$thmbFile,80);
} } } } } } }
function getNormalImage($file){
$base = substr($file,0,strrpos($file,'_th.jpg'));
if (file_exists($base.'.jpg')) return $base.'.jpg';
elseif (file_exists($base.'.jpeg')) return $base.'.jpeg';
else return "";
}
function displayPhotos(){
global $columns;
generateThumbnails();
$act = 0;
// Open the actual directory
if ($handle = opendir(".")) {
// Read all file from the actual directory
while ($file = readdir($handle)) {
// Check whether tha actual item is a valid file
if (is_file($file)){
// Check whether the actual image is a thumbnail
if (strpos($file,'_th.jpg')){
++$act;
if ($act > $columns) {
echo '</tr><tr>
<td class="photo"><a href="/albums/jeep-cooper-stt-tires/'.getNormalImage($file).'">
<img src="/albums/jeep-cooper-stt-tires/'.$file.'" alt="'.$file.'" /></a></td>';
$act = 1;
} else {
echo '<td class="photo"><a href="/albums/jeep-cooper-stt-tires/'.getNormalImage($file).'">
<img src="/albums/jeep-cooper-stt-tires/'.$file.'" alt="'.$file.'" /></a></td>';
} } } } } }
?>

Does anyone have any ideas?
(The script is used by putting it in a directory with images, it makes the thumbs.)
Thanks for any help!
