Help with createimagefromjpeg not working

[Dynamo]

Hi yet again,

I am trying to resize a previously uploaded image on my server to a thumbnail
but am getting a fatal error message as follows

Fatal error: Call to undefined function: imagecreatefromjpeg() in
\\mydomain\resizeimage.php on line 10

This would imply that the function is not available from mywebhosts and yet
according to the php manual it has been available since ver 3 of php.

Note that php is installed on my webhosts server and not my local PC.

As always any help appreciated.

Regards
Dynamo

Image functions require the GD extension enabled.
You can check what's enabled writing a file (name it like phpinfo.php) with:
<?php
phpinfo();
?>
and calling it (http://yourdomain.com/phpinfo.php) with a browser.
It sholud display a lot of info, including what extensions are
available. If there is not a 'gd' item, you're out of luck (unless you
talk your host into installing the thing).

I think the GD-libs are needed too to use imagefunctions.
(On Linux at least.)
use php_info() to be sure.
It should be listed somewhere.

When in doubt, just contact your serviceprovider. They should know.
