Dear Experts,
Seems like I can't use any of the followings even
though I'm running PHP 4.3.2-RC1:
* imagecreatefromjpeg
* imagecopy
* etc.
Am I right the gd-2.x has already integrated with
PHP 4.3.2-RC1 and the gd also has the jpeg integrated?
Or, should do I have to bring in the jpeg-6x myself?
If I need to bring in the jpeg-6x myself, should I
install it within the ext/gd sub-dir?
Thing wanted to do: create a separate thumbnail jpeg
file from an org. jpeg file. Any better idea?
Please advice.
Thanks in advanced.
