ImageCreateFromJPEG fails if path contains apostrophe ?

[tim.landgraf@googlemail.com]

hi there,

i am experiencing a strange problem. i am iterating through a given
directory, selecting only jpg - images that are then resized and
inserted into a database. everything works, but if there is a file
with an apostrophe in it the GD function @ImageCreateFro mJPEG fails.
anyone knows this problem and possible workarounds?

thank you,
tim

here is the code
[list.php]
....
while ( $file = readdir($dirhan dle) )
{
echo "
....
<a href="show_imag e.php?path='.ra wurlencode($dir .'/'.$file).'">sho w</
a><br />
....
";
}
....

[show_image.php]
....
if ( $image = LoadJpeg(rawurl decode($_GET["path"])))
{
header("content-type:image/jpeg");
imagejpeg($imag e);
}
....

with function LoadJpeg defined as:

//taken from http://www.hpserver.de/php/function....efromjpeg.html
function LoadJpeg ($imgname) {
$im = @ImageCreateFro mJPEG ($imgname); /* Versuch, Datei zu öffnen
*/
if (!$im) { /* Prüfen, ob fehlgeschlagen
*/
$im = ImageCreate (150, 30); /* Erzeugen eines leeren
Bildes */
$bgc = ImageColorAlloc ate ($im, 255, 255, 255);
$tc = ImageColorAlloc ate ($im, 0, 0, 0);
ImageFilledRect angle ($im, 0, 0, 150, 30, $bgc);
/* Ausgabe einer Fehlermeldung */
ImageString($im , 1, 5, 5, "Fehler beim Öffnen von: $imgname",
$tc);
}
return $im;
}

Since you are passing the path of the file using GET variables, you may
be a victim of "magic quotes". See:

http://www.php.net/manual/en/ref.info.php#ini.magic-quotes-gpc

http://www.php.net/manual/en/function.stripslashes.php

To be sure, echo the filename and see if it is correct.
