PHP and GD

[DARKGuy]

Greetings! 🙂

Well, my hosting has this kind of GD

gd
GD Support enabled
GD Version bundled (2.0.28 compatible)
GIF Read Support enabled
GIF Create Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

And my localhost server has this kind of GD

gd
GD Support enabled
GD Version bundled (2.0.15 compatible)
FreeType Support enabled
FreeType Linkage with freetype
GIF Read Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

I'm the one with the lower version, so I bet the old commands would work the same way in the one of my hoster, but it isn't that way.

In my host, I get this error:

Warning: imagecopyresized(): supplied argument is not a valid Image resource in /home/3852570779/dbfree/web/site/thumb.php on line 39

Fatal error: Call to undefined function: imagejpeg() in /home/3852570779/dbfree/web/site/thumb.php on line 40

Thumb.php is this:

<?
$pics=$_GET['file'];
$me=resizepics($pics,'100','100');
echo $me;
function resizepics($pics, $newwidth, $newheight){
	$newwidth=120;
	$newheight=120;
     if(preg_match("/.jpg/i", "$pics")){
           header('Content-type: image/jpeg');
     }
     if (preg_match("/.gif/i", "$pics")){
           header('Content-type: image/gif');
     }
     list($width, $height) = getimagesize($pics);
     if($width > $height && $newheight < $height){
       $newheight = $height / ($width / $newwidth);
     } else if ($width < $height && $newwidth < $width) {
       $newwidth = $width / ($height / $newheight);   

     } else {
       $newwidth = $width;
       $newheight = $height;
   }
   if(preg_match("/.jpg/i", "$pics")){
   $source = imagecreatefromjpeg($pics);
   }
   if(preg_match("/.jpeg/i", "$pics")){
   $source = imagecreatefromjpeg($pics);
   }
   if(preg_match("/.jpeg/i", "$pics")){
   $source = Imagecreatefromjpeg($pics);
   }
   if(preg_match("/.png/i", "$pics")){
   $source = imagecreatefrompng($pics);
   }
   if(preg_match("/.gif/i", "$pics")){
   $source = imagecreatefromgif($pics);
   }
   $thumb = imagecreatetruecolor(120,120);
   imagecopyresized($thumb, $source, 0, 0, 0, 0, 120, 120, $width, $height);
   return imagejpeg($thumb);
   if(preg_match("/.jpg/i", "$pics")){
   return imagejpeg($thumb);
   }
   if(preg_match("/.jpeg/i", "$pics")){
   return imagejpeg($thumb);
   }
   if(preg_match("/.jpeg/i", "$pics")){
   return imagejpeg($thumb);
   }
   if(preg_match("/.png/i", "$pics")){
   return imagepng($thumb);
   }
   if(preg_match("/.gif/i", "$pics")){
   return imagegif($thumb);
   }
 }
?>

Could someone help me here and tell me what's wrong here? it works correctly on my comp but not in the hoster, what it's wrong with it? If anyone could, well, thanks in advance 🙂

you are using the imagejpeg function and the host doesnt have php compiled with jpeg support. they'll need to compile --with-jpeg-dir=DIR where that points to the jpeg libraries.

[DARKGuy]

I see, so there are no workarounds for that either?

[drew010]

no not really. since php isnt compiled with jpeg support the function wont exist unless they first install the jpeg files and then recompile.
the imagecopyresized problem is happening because the images werent succesfully created due to no jpeg support. that problem will be gone once jpeg is enabled.

Ah I see... too bad 🙁 oh well, thanks 🙂
