GD lib testing!

[Anon]

hi, I am clearly a newbie to this php stuff!
I think I have installed the GD_lib onto the server (apache) and it is running php 4.0 as cgi.
I can't tell if it is working right!
I have some script that I am using for a project to write text onto an image. but it keeps having an error along the lines of
Call to undefined function: imagecreatefromjpg()

and then tells me the file name.
what am I doing wrong?
and does someone have a bit of code that will show me if it works!!!
cheers

You can try a simple function that will take an existing image and make a copied version in a different size.

<?
$size = GetImageSize("imagefile.gif");
$im_in = ImageCreateFromGif("imagefile.gif");
$im_out = ImageCreate($size[0] 4, $size[1] 4);

ImageCopyResized($im_out, $im_in, 0, 0, 0, 0 $size[0] 4, $size[1] 4
$size[0], $size[1]);
ImageGif($im_out, "newimagefile.gif");
ImageDestroy($im_in);
ImageDestroy($im_out);
?>

<img src="imagefile.gif" border="0">
<img src="newimagefile.gif" border="0">
