Image Resize problem

Anon

Hi there im using php 4 with gd on freebsd.
Im having problems resizing some jpeg images using gd.
I can do the image upload perfect, and thumbnail creation too. But sometimes i get an error that looks like this
"is not a valid JPEG file"

Anyone has an idea of why is this happening?

I see no problem with that images, i can open them in any image manipulation software and even in IE.

I think it may be a problem with the jpeg headers.. but i dont have idea about it.

Anyone can help me with this?

Thnx in advance

In your script that does the imagejpeg($im) line, call:

header("Content-type: image/jpg");
or
header("Content-type: image/jpeg");

before any (and I mean ANY) output is printed, and it should work.

Hi dave, thanks for your help but i guess it wasnt my problem.

I mean my problem is not showing the image, it is when i try to create the a thumbnail from the original uploaded img.

The function imagecreatefromjpeg() is giving the error "is no a valid jpeg image"

Im using high resolution images. is there a problem with big image sizes? 1 mb+

here is a portion of my code

$imagefile=(PATH_TMP . "/".$customer_id ."/" .$image_name);
$src_img = imagecreatefromjpeg($imagefile);

$iWidth = imagesx($src_img);
$iHeight = imagesy($src_img);

$new_w = imagesx($src_img)/4;
$new_h = imagesy($src_img)/4;

$dst_img = imagecreate($new_w,$new_h);
imagecopyresized($dst_img,$src_img,0,0,0,0,$new_w,$new_h,imagesx($src_img),imagesy($src_img));
imagejpeg($dst_img, PATH_TMP . "/". $customer_id ."/" ."t".$image_name);

thanks in advance
