I have image field, and I want to do resize in 4 different size
In User Guide I found below property for image,
$upload_path = assets_server_path('authors/', 'images');
$fields['avatar_upload'] = array('type' => 'file', 'upload_path' => $upload_path, 'overwrite' => TRUE);
But didn't found anything related image resizing. So How Can I handle the image resizing?
If there is nothing inbuilt then please advise me, Where can I set my resizing code? So once Form submit then I can put my code there.
