Is there a way to make WordPress process Full size images, which by default it leaves unmodified?

Unmodified as in not resizing the picture? Your question is a bit ambiguous.– mystlineApr 13, 2012 at 8:45

Problem: people upload huge images and WordPress leaves them as they are. I need to find a way to optimize Full size images, but there is no such option in the admin area.– DanApr 13, 2012 at 10:07

Under Media, you have 3 sizes options by default.– WyckApr 13, 2012 at 15:09

yup, but I need to compress the "Full size" image as the title and my question obviously state.– DanApr 14, 2012 at 4:26

Yes, there is.
Found here:
http://www.wprecipes.com/how-to-automatically-use-resized-image-instead-of-originals
It will replace the original picture with the large size, defined in Media Settings (/wp-admin/options-media.php).
Here's the code:
add_filter('wp_generate_attachment_metadata','replace_uploaded_image');
function replace_uploaded_image($image_data)
{
// if there is no large image : return
if ( !isset($image_data['sizes']['large']) )
return $image_data;
// paths to the uploaded image and the large image
$upload_dir = wp_upload_dir();
$uploaded_image_location = $upload_dir['basedir'] . '/' . $image_data['file'];
$large_image_location = $upload_dir['path'] . '/' . $image_data['sizes']['large']['file'];
// delete the uploaded image
unlink($uploaded_image_location);
// rename the large image
rename($large_image_location, $uploaded_image_location);
// update image metadata and return them
$image_data['width'] = $image_data['sizes']['large']['width'];
$image_data['height'] = $image_data['sizes']['large']['height'];
unset($image_data['sizes']['large']);
return $image_data;
}
It is possible to use it with a custom size:
add_image_size( 'new-large', 1600, 1200 );
Changing all the occurrences of $image_data['sizes']['large'] in the original code with $image_data['sizes']['new-large']
