Server B handling add_image_size() differently than Server A

Question

I'm curious what dependencies add_image_size() has because I just copied a theme over to a new server and began adding thumbnails to custom post types only to find out that my request for hard-cropping is being ignored, and the images are kept proportional.

functions.php

...
set_post_thumbnail_size( 80, 80, true );
add_image_size( 'micro', 32, 32, true);
add_image_size( 'featured', 340, 225, true );
add_image_size( 'videowide', 460, 225, true );
...

On my local server (WAMP Server on Windows Vista) the true is respected, and the images are cropped in such a way that extra pixels are lost - edges aren't respected. On my live server (CloudLinux Server 5.5 x64), the images are kept proportional.

Is there some gdlibrary dependencies or something I am needing to change on the live server to get the expected results?

Answer 1

This particular issue was caused by an environment missing GD. After installing GD on the server, the issue was resolved. Of course you will need to go back and re-submit your thumbnails to have correct cropping, or use a plugin to retroactively recreate your thumbnails.

Answer 2

Your question reminded me of a time when I was playing with the Wordpress 3.0 beta and ran into a similar issue. Not sure if this will help you or not, but I stumbled across this post in the Wordpress forums.

Hi guys.

I´ve spent a lot of my day looking for a solution for this issue and here is the solution, in front of my eyes! Thanks to stylishbeachbum and Alex Mansfield. Yeah, the issue depends of the server. I´m using apache/php/mysql on Windows XP and the php_hd2 extension wasn´t enabled.

I´ve enabled that and now is working.

Thank you guys.

I'd love to know if this is the case. I had a few experiments in my Wordpress lab using custom image sizes, but abandoned my tinkering when I mas met with similar oddities.
