RE: [PHP] Re: Can't display PNG images
Echoing text to the screen is a very useful debugging tool when creating images from php, if you type the full location of the image script in the address bar, rather than specifying it as an image that is opened by a html page. If you do this Teresa, you should get the PHP error message, and if you give this to us it would help.

Thank you so much for your responses. Thanks for any response! I now the GD libraries with PNG support. However, the image is still broken. I looked at the apache server error log and this is what showed up when I run zero.php(See below): libpng warning: Application was compiled with png.h from libpng-1.0.8 libpng warning: Application is running with png.c from libpng-1.2.1 gd-png: fatal libpng error: Incompatible libpng version in application and library [Tue Mar 12 20:09:43 2002] [notice] child pid 30296 exit signal Segmentation fault (11) Action Taken o Deleted old lipng* files in /usr/lib o Compiled libpng-1.2.1 and installed it in: /usr/lib o recompiled and installed php 4.1.2(Upgraded from 4.1.1) -- CODE -- zero.php img src=one.php alt=a PHP generated image one.php --- ?php header(Content-type: image/png); $image = imagecreate( 200, 200 ); imagepng($image); ? -Original Message- From: Alastair Battrick [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 12, 2002 7:05 AM To: Jordan S.

Hi You will probably have to recompile gd as well. Tom At 11:33 AM 13/03/2002, Narvaez, Teresa wrote: Thank you so much for your responses. Thanks for any response!
