Hi there all!
I am new to this php stuff, and have found a thumbnail script, that takes a dir as an argument, and creates a page with thumbnails out of the images avalible in the directory given. The only problem is that the images are never rendered...
The script looks like this:
(http://evilwalrus.com/viewcode.php?codeEx=324)
<?
if( ! isset( $filename ) ){
define( "SIZE" , 120 ) ;
define( "COLNUM" , 6 ) ;
$dir = ($dir)?$dir:"." ;
?>
<head>
<title>Browse <?= $dir ?></title>
<style type="text/css">
<!--
table{
width:100%;
}
td{
text-align:center;
}
img{
border:none;
}
-->
</style>
</head>
<body>
<table>
<?
$dd = opendir($dir) ;
for( $i = 0 ; $filename = readdir($dd) ; ){
if( is_file("$dir/$filename") ){
if( $imgSize = getImageSize("$dir/$filename") ){
$w0 = $imgSize[0] ;
$h0 = $imgSize[1] ;
$imgType = $imgSize[2] ;
$ratio = $w0 / $h0 ;
if( $ratio > 1 ){
$w1 = SIZE ;
$h1 = ( SIZE * $h0 ) / $w0 ;
}
else{
$w1 = ( SIZE * $w0 ) / $h0 ;
$h1 = SIZE ;
}
$params = sprintf( "filename=$dir/$filename&w0=$w0&h0=$h0&imgType=$imgType&h1=%d&w1=%d" , $h1 , $w1 ) ;
if( ! ( $i % COLNUM ) ){
echo "\n<tr>\n" ;
}
?>
<td>
<a href="<?= "$dir/$filename" ?>">
<img src="./browser.php?<?= $params ?>" style="width:<?= $w1 ?>;height:<?= $h1 ?>;"></a><br>
<?= "$filename : $w0 x $h0" ?>
<?
$i++ ;
}
}
}
?>
</table>
</body>
<?
closedir($dd) ;
}
else{
switch($imgType){
case 1:
$imgType = "gif" ;
break;
case 2:
$imgType = "JPEG" ;
break;
case 3:
$imgType = "png" ;
break;
default:
break;
}
header("Content-type: image/$imgType") ;
$tImg = imageCreate( $w1 , $h1 ) ;
$imgOpenFunc = "imageCreateFrom".$imgType ;
$imgSendFunc = "image".$imgType ;
$img = $imgOpenFunc("$filename") ;
imageCopyResized( $tImg , $img , 0 , 0 , 0 , 0 , $w1 , $h1 , $w0 , $h0 ) ;
imageDestroy($img) ;
$imgSendFunc($tImg) ;
}
?>
And when I take a look at the URL of an image, it looks like: http://www.webpage.com/images/PIC00020.jpg&w0=1024&h0=768&imgType=2&h1=90&w1=120
Does any one has a clue??
thanks in advanced
