I am using TimThumb to crop image in my wordpress theme, but by default you can only use images hosted in your website in TimThumb, because it uses relative path. (perhaps the author want to avoid other users from using your server resources, bandwidth) I manage to edit the timthumb.php to make it able to crop images hosted on other websites, but now any people can use the timthumb.php on my website to generate thumbnail at their website. Should I be worry about this? or is there any perfect solution for this? Thanks.
