Script Not Working

[Ilya020]

Hello guys,

I have these two PHP scripts; gen.php and thumbs.php.
This is for an images gallary where gen.php produces the thumbnails and thumbs.php displays them.

I am trying to get this to work but the images keep getting broken. http://sig11.zemos.net/test/thumbs.php

here is the source for gen.php

<?php 

$t_width = 100; // Thumbnail width 

// get and display jpeg images 
if(stristr($QUERY_STRING,".jpg")){ 
header("Content-type: image/jpeg"); 
$srcimage = imagecreatefromjpeg($QUERY_STRING); 
$width = imageSX($srcimage); 
$height = imageSY($srcimage); 
$newh1= $height / $width; 
$newh2= $newh1 * $t_width; 
$destimage = imagecreate($t_width,$newh2); 
imagecopyresized($destimage,$srcimage,0,0,0,0,$t_width,$newh2,$width,$height); 
ImageJPEG($destimage); 
ImageDestroy($destimage); 
} 


// on a problem geneterate an image with ERROR in it 
/*else { 
$im = imagecreate(100,100); 
$blue = imagecolorallocate($im,0,0,200); 
$red = imagecolorallocate($im,255,0,0); 
imagestring($im,2,2,5,"ERROR",$red); 
imageGIF($im); 
imagedestroy($im); 
} */

?>

Here is thumbs.php

<?php 
// Set variables 
$default_dir = "./images"; // Relative to current location 


// Directory Scan 
if(!($dp = opendir($default_dir))) die("Cannot open $dir"); 
// Place images into image tag 
while($file = readdir($dp)){ 
    if($file != '.' && $file != '..' && stristr($file,"jpg")) echo "<a 
href=\"$default_dir/$file\"><img 
src=\"./gen.php?$default_dir/$file\"></a>\r\n"; 
} 

closedir($dp); 


?>

Any ideas?

Thank you

Ilya

Here's a question, and keep in mind I know close to nothing about php, but.

There's this little dealy:

$srcimage = imagecreatefromjpeg($QUERY_STRING);

Now I don't know imagecreatefromjpeg from a hole in the wall, is that built in or did you write it? Either way, what file extention does it use for the final image .jpeg or .jpg ?

because later, when displaying the images, you look only for .jpg

in the thumbs.php here:

 if($file != '.' && $file != '..' && stristr($file,"jpg"))

Perhaps it's not finding the right pictures because you're looking for the wrong extention (.jpg instead of .jpeg)?

In the same vein when you have an error it seems like you're creating a .gif and then again looking for .jpg?

But then again I could be way off, good luck!
