checking if image generation is supported and image resize

[mr_burns]

Hi there,

How would I check if image generation is supported on my server? I
used phpinfo() but didnt know what to look for.

Also, I just want to resize image when they are uploaded using PHP. Is
this possible? What is the quality like after resize? Cheers

Look for a section titled 'gd'. This corresponds to the following:

Potentially quite poor with the simple function above. But for better results
see: http://uk2.php.net/manual/en/functio...yresampled.php

GD is also not the fastest solution for resizing photos (see [1] below);
consider looking into ImageMagick and calling that as an external process.
(There's also a PHP module to interface to the library that could remove the
need for an external process).
