Can I have a moment? I got stucked in here :\

[Q8iEnG]

Hi all my friends :)

I hope you're all doing great :)

I need a small help from you, and I hope you'll not let me down *shy*

I have a script that it shows all images in the directory of my site under the folder (Albums)

for (.jpg) only!

So, I tried to make this script accepts also (.png) formats

Actually, What I did is inserting this code

elseif ( preg_match ( '#.png$#i', $f ) )
            {
                $info = getimagesize ( $path . $f );
                $dimension = $info[0] . 'x' . $info[1];
                $contents['images'][] = array ( 'name' => $f, 'dimension' => $dimension, 'modified' => filemtime ( $path . $f ), 'size' => filesize ( $path . $f ) );

to this code in *FUNCTION.PHP*
the code after inserting my code

function dir_get_contents ( $root, $dir )
{
    $dir = $dir != '' && $dir != '/' ? trim ( $dir, '/' ) : '';
    $path = $root . $dir . '/';
    $h = opendir ( $path );
    if ( !$h )
    {
        exit ( 'Unable to open ' . $path );
    }

    $contents['images'] = array( );

    $contents['albums'] = array ( );

    while ( false != ( $f = readdir ( $h ) ) )
    {
        if ( $f != '.' && $f != '..' )
        {
            if ( is_dir ( $path . $f ) )
            {
                $info = dir_info ( $path . $f );

                $contents['albums'][] = array ( 'name' => $f, 'albums' => $info['dirs'], 'images' => $info['files'] );
            }
            elseif ( preg_match ( '#.jpg$#i', $f ) )
            {
                $info = getimagesize ( $path . $f );
                $dimension = $info[0] . 'x' . $info[1];
                $contents['images'][] = array ( 'name' => $f, 'dimension' => $dimension, 'modified' => filemtime ( $path . $f ), 'size' => filesize ( $path . $f ) );
            }
            elseif ( preg_match ( '#.png$#i', $f ) )
            {
                $info = getimagesize ( $path . $f );
                $dimension = $info[0] . 'x' . $info[1];
                $contents['images'][] = array ( 'name' => $f, 'dimension' => $dimension, 'modified' => filemtime ( $path . $f ), 'size' => filesize ( $path . $f ) );
            }
        }
    }
    return $contents;
}

Now, I ended up with an error
saying

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg: JPEG library reports unrecoverable error: in /home/********/functions.php on line 217

Now, I tried to do my best in the problem which occures in the line 217
BUT, I couldn't do anything :\

this is the code in line 217 which causes the problem (this code generates thumbnails for the images)

function create_thumbnail ($source, $destination, $new_width = 100, $new_height = 'auto', $quality = 85)
{
    $im_src = imagecreatefromjpeg($source);
    if (!$im_src) return;
    $im_width = imagesX($im_src);
    $im_height = imagesY($im_src);
    if( !is_int($new_width) && is_int($new_height) )
    {
        // resize the image based on height
        $ratio = $im_height / $new_height;
        $new_width = floor($im_width / $ratio);
    }
    elseif( is_int($new_width) && !is_int($new_height) )
    {
        // resize the image based on the width
        $ratio = $im_width / $new_width;
        $new_height = floor($im_height / $ratio);
    }
    // create blank image
    $im = imagecreatetruecolor($new_width, $new_height);
    imagecopyresampled($im, $im_src, 0, 0, 0, 0, $new_width, $new_height, $im_width, $im_height);
    imagejpeg($im, $destination, $quality);
    imagedestroy($im);
    imagedestroy($im_src);
}

I wonder if anyone can help me fix this problem, i'll be much more appreciated :)

by the way, this is the WHOLE code for the *FUNCTION.PHP*

I don't have the time to give you an in depth answer tonight, but I've attached a set of functions that create thumbnails with PHP which I developed semi-recently. Take a look and see what I did that's different from your script, or use the functions if they work for you.

I believe the usage of the functions is (hopefully) self explanatory ...

Hope it helps

Since you are trying to use .png files, $im_src = imagecreatefromjpeg($source); will not work. Because, imagecreatefromjpeg will work for jpeg files !
If you want to work with .png files , you should use imagecreatefrompng .
