Check out the PHP dl() function:
http://www.php.net/dl
It lets you load an extension at run-time, so if you can compile the
newer version of GD, you may be able to download that directly. Only
thing I'm not sure about is if you can override an already-loaded
extension by downloading a newer version of the same extension. Maybe
if you simply named it something different -- gd-1.8.3.so, for example.
Can anyone confirm whether this would work or not?
