GD, jpeg image creation

matt_greenhalgh

HI,

Im trying to use the GD functions to eventually create thumbnails of images that users have uploaded.

But at the moment i am having problems with geting it to just output an image.

Heres the code i have

<?php
Header("Content-Type: :mage/jpeg");
$img_name = "test.jpg";
$src_img = ImageCreateFromJPEG($img_name);
ImageJPEG($src_img);
ImageDestroy($src_img);
?>

When running this code I get no output (image is not created as far as i can see)

I have checked the status of GD and php and they are both installed properly (with jpeg support).

As for this problem i am stumped, any ideas

Thanks

Matt

Header("Content-Type: :mage/jpeg");

should be

Header("Content-Type: image/jpeg");

you might also need to use the full path to the image (e.g. /httpd/vhosts/yourdomain.com/images/whatever.jpg)

Hi,

Thanks for your help, I corected the header and tried both relative and absolute addressing of the image but i get the same error

from what i can see the function "ImageJPEG" dosn't seem to be working.

Does anybody know why this would be?

Thanks

Matt

I have the same problem.

I have tried all of the gd lib examples in the manual, and none of them work, even though phpinfo() tells me that gd is installed properly and supports everythin.
