Rodrigo,
I've been struggling with this for some time, so here goes:
The php4 builds do not support .gif files, you'll need to change your files
to .jpg or .png format, or use php3 (I can't change to php3).
I use imagecreate() func. before imagecreatefromjpeg() func. because if I
didn't do this, the added text would be gray regardless of the desired
color.
The mysql portion is solid and yields the desired results.
However, I'm having trouble with something related to the
imagecreatefromjpeg() func., I get a server error (500) on some images
regardless of their size. This is the only error produced by the func. and
it is maddening. From experimentation, I believe that there's something
wrong with the .jpg files, the .jpg file upload, or the phase of the moon.
Good luck,
Hugh

Subject: [PHP] Change gif image with php
Hi list
I have some buttons made in photoshop in .gif format. This buttons have
round corner, feather, multiple colors etc. There's a way to open it with
php and write some text to it. I know that is possible to create images,
but
what about to change them??? I need to do this because the text that will
fill the buttons come from mysql and change everyday.
Thank's in advance
Rodrigo
ps: If someone want to see the button I'm talking look in
http://www.celebnet.com.br/home.php under the AS ++.
