Hi,
Great script!
I just want it to read the pictures from a different folder.
Can’t get it to work. Anyone did that?
I got the thumbnails to be show, when the full-size pictures are in a different folder, by changing:
if ( $handle = opendir(“.”) ) {
to
if ( $handle = opendir(“myimages/”) ) {
But stuck after that
Any help would be great!

Any chance of putting a comment under each picture?

Hello Sir
I am new to PHP. I have downloaded and tried ur code. I got the following error

Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 5060 bytes) in C:\xampp\htdocs\phpgallery\index.php on line 37

The index.php file is as follows

# SETTINGS
$max_width = 100;
$max_height = 100;

function getPictures() {
global $max_width, $max_height;
if ( $handle = opendir(".") ) {
$lightbox = rand();
echo '’;
while ( ($file = readdir($handle)) !== false ) {
if ( !is_dir($file) ) {
$split = explode(‘.’, $file);
$ext = $split[count($split) - 1];
if ( ($type = getPictureType($ext)) == ” ) {
continue;
}
if ( ! is_dir(‘thumbs’) ) {
mkdir(‘thumbs’);
}
if ( ! file_exists(‘thumbs/’.$file) ) {
if ( $type == ‘jpg’ ) {
$src = imagecreatefromjpeg($file);
} else if ( $type == ‘png’ ) {
$src = imagecreatefrompng($file);
} else if ( $type == ‘gif’ ) {
$src = imagecreatefromgif($file);
}
if ( ($oldW = imagesx($src)) < ($oldH = imagesy($src)) ) {
$newW = $oldW * ($max_width / $oldH);
$newH = $max_height;
} else {
$newW = $max_width;
$newH = $oldH * ($max_height / $oldW);
}
$new = imagecreatetruecolor($newW, $newH);
imagecopyresampled($new, $src, 0, 0, 0, 0, $newW, $newH, $oldW, $oldH);
if ( $type == 'jpg' ) {
imagejpeg($new, 'thumbs/'.$file);
} else if ( $type == 'png' ) {
imagepng($new, 'thumbs/'.$file);
} else if ( $type == 'gif' ) {
imagegif($new, 'thumbs/'.$file);
}
imagedestroy($new);
imagedestroy($src);
}
echo '‘;
echo ”;
echo ‘‘;
}
}
echo ”;
}
}
?>

Pictures

#pictures li {
float:left;
height:px;
list-style:none outside;
width:px;
text-align:center;
}
img {
border:0;
outline:none;
}

When I commented line no. 37 i.e. $src = imagecreatefrompng($file);
I got the pictures as thumbnails with following warnings.

Warning: imagesx(): supplied argument is not a valid Image resource in C:\xampp\htdocs\phpgallery\index.php on line 41

Warning: imagesy(): supplied argument is not a valid Image resource in C:\xampp\htdocs\phpgallery\index.php on line 41

Warning: imagedestroy(): supplied argument is not a valid Image resource in C:\xampp\htdocs\phpgallery\index.php on line 58

When I click on the thumbnails it shows the original pictures.

I don’t know what to do. GD Library is enabled
I have XAMPP for Windows Version 1.6.7
php version 5.2.6
Plz Help.

What if I want to use other type of file beside picture format? Like .doc or .pdf, is there any way to do so?

looks like i am not the only one with the directory bug,
well i have managed to get it to create the /thumbs/ folder inside images (one i that assigned!) but it will not create the thumbs in it,
if i assign the alt tag as the $file, you can see a link (text ) to the image but then again no thumbs inside the thumbs folder…..
for any one whom wants to see the script modified by me here it is (BTW i am a total noob at PHP)

# SETTINGS
$max_width = 100;
$max_height = 100;

function getPictures() {
global $max_width, $max_height;
if ( $handle = opendir("./images") ) {
$lightbox = rand();
echo '’;
while ( ($file = readdir($handle)) !== false ) {
if ( !is_dir($file) ) {
$split = explode(‘./images/’, $file);
$ext = $split[count($split) - 1];
if ( ($type = getPictureType($ext)) == ” ) {
continue;
}
if ( ! is_dir(‘./images/thumbs’) ) {
mkdir(‘./images/thumbs’);
}
if ( ! file_exists(‘./images/’.$file) ) {
if ( $type == ‘jpg’ ) {
$src = imagecreatefromjpeg(‘./images/’.$file);
} else if ( $type == ‘png’ ) {
$src = imagecreatefrompng(‘./images/’.$file);
} else if ( $type == ‘gif’ ) {
$src = imagecreatefromgif(‘./images/’.$file);
}
if ( ($oldW = imagesx($src)) < ($oldH = imagesy($src)) ) {
$newW = $oldW * ($max_width / $oldH);
$newH = $max_height;
} else {
$newW = $max_width;
$newH = $oldH * ($max_height / $oldW);
}
$new = imagecreatetruecolor($newW, $newH);
imagecopyresampled($new, $src, 0, 0, 0, 0, $newW, $newH, $oldW, $oldH);
