resize high res images problem

[c1zorro]

Im using php gd to resize images. Im having problems with large images 1mb+

I get an "invalid jpeg file" error

Is there a maximum size that can be used?

It works fine with small images.

thanx in advance

Hey bud,

I'm having problems getting my resize code to work.

Does your code look anything like this?

<?php
// resize
Header("Content-type: image/jpeg");
$original = "big.jpg";

$small = ImageCreate(100,100);
ImageCopyResized($small,$original,0,0,0,0,100,100,500,500);
Imagejpeg($small, "new_big.jpg");

ImageDestroy($original);

?>

what error are you getting?

I'm getting Call to an undefined function :createimage()

I assume I may be missing a library?
