[geeklog-devel] Image resizing with gdlib

[Tom Willett]

I was playing with the automatic image resizing using gdlib this morning and 
noticed something wrong.

The image resize works correctly but the link in the article is wrong.  The 
image is converted to png but the article points to the picture as a gif.  
The image is correctly converted to png and resized and resides in the image 
directory, the link is simply wrong.  Here is the debug information:

Thu 30 Sep 2004 08:35:17 AM EST - Debug: File size for 2milmap.gif is 14617 
bytes

Thu 30 Sep 2004 08:35:17 AM EST - Debug: Resizing image, 
factor=0.37974683544304 
Thu 30 Sep 2004 08:35:17 AM EST - Debug: Image, 2milmap.gif was resized from 
790x423 to 300x160 

Am I missing a setting somewhere?

I set config.php to:

$_CONF['image_lib'] = 'gdlib';

and left the rest default.

Running on Fedora Core 2

PHP 4.3.8
Apache 2.0.51 
GD 2.0.23 with gif, jpg, and png support
