Error, why, how to resize it correctly???
src:

if (isset($x))
$detail_max_x=$ x;
else
$detail_max_x = 300;

if (isset($y))
$detail_max_y=$ y;
else

$type = "jpg";

// Orginalbild
$pic=$src;

// Bilddaten feststellen
$size=getimages ize($pic);
$faktor_y=$size[0]/$detail_max_y;

Your version of PHP is probably compiled with memory limit support, which
defaults to 8M. Just increase the allowed memory (e.g. by adjusting the
memory_limit directive in your php.ini file to 16M) and it will work fine.

Well, JPEG-images *are* 24-bit bitmaps. So an image at size of
3000x3000 pixels *will* require 25.7MB of memory. In your script, the
memory required to finish the script depends on the size of $altesBild
(because it *gets* loaded into memory) even though $neuesBild would
only be quite small.
