So, today I “updated” wordpress to match my digital camera. Why did I do this? Well easy! Currently wordpress supports thumbnails for uploaded pictures if the file is <= 3 megapixel in size. Not megabytes or something, megapixel.
I updated the wp-admin/includes/image.php file to be able to upload files (and thumbnail them) if they are bigger then that size. This way I can normally add my digital photos that were created by my Sony Alpha 100 camera.
What did I do?
Edit wp-admin/includes/image.php and search/replace the following line (at the moment of writing this is line 150 with wordpress 2.3.1)
$max = apply_filters( 'wp_thumbnail_creation_size_limit', 3 * 1024 * 1024, $attachment_id, $file );
with the following line:
$max = apply_filters( 'wp_thumbnail_creation_size_limit',
EDIT: Please take notice that you might run into server errors, because of PHP running out of it's allowed memory size. You can set these values in ``php.ini``.
