Subject: Re: [PHP] Create Thumbnails from image
Hey Julien!
Thanx for the code! Your posting from yesterday helped me out. Actually I
was on the right path all along but hadn't activated the GD-extension in my
php.ini and so I just got errors and grew _pretty_ annoyed by it. Then after
I got your message from yesterday giving med the same errors I realized that
there were somethin' cookin'. After activating the GD-extension and
restarted Apache your snippet worked fine and eventually mine too.
Thanx again for your effort, it would have been better though if we all had
sent this to the newsgroup. More people would have had a chance to see it
there...
Have fun
Regards
Kjell
