Image Resize does not work

[Sandwick]

I am trying to change the size of a drawing so they are all 3x3.

the script below is what i was trying to use to cut it in half ... I
get errors.

I can display the normal picture but not the results of the picture
half the size. The PHP I have installed support 1.62 or higher. And
all I would like to do is take and image and make it fit a 3x3.

Any suggestions to where I should read or look would be appreciated.

TIA

Error messages can be your greatest friend. Is the file 13727.jpg in
/var/www/html? That's where it's probably looking, since that's where
the PHP script is and you didn't provide an absolute path in the file
name. You should probably do that, something like:

$IMG_BASE = "/var/www/html";
$FullImgName = "$IMG_BASE/$image.jpg";

thanks for the input that eliminated 3 of the errors !

I now have the file identified, but it will still not display the
picture in half. It now complains about the following?

It looks like I do not have the right version, but my phpinfo() tells
me I have 1.62 or higher support.

See error below.

Am I missing something? You have 1.62 or higher. The error message says you need 2.0. Presumably, you have
something between 1.62 and 2.0. You'll need to upgrade.
