good question, this is the part that takes care of the thumbnail rendering:

PHP Code:


                //determine size for thumbnail
                $img2w = ($img1w >100 ) ? 100 : $img1w;
                $img2h =  round($img2w/$ratio); //rounded width/ratio

    //create the thumbnail
                $attachthumb = imagecreatetruecolor($img2w,$img2h);
                imagecopyresampled($attachthumb,$file1,0,0,0,0,$img2w,$img2h,$img1w,$img1h); 

        ob_start();        
        
                //all thumbnails are stored as png
                $thumbrendered = $vbattachthumb.$fnnoext."_thu.png";
                imagepng($attachthumb,$thumbrendered);

        ob_end_clean(); 


I create the thumbnails as PNG files, same thing worked for creating the avatar pics in another script; instead for thumbnails in the forum attachments I rendered them in jpeg; should i pass to jpeg instead?
