I explain my wish.
When I upload some photos, I resize them before because I know that a 2048x1024 pic take 1Mo on my server ! But, on my website, a lot of people add new pics and they can't or they don't know how to resize before so I have some bigs photos on my gallery.
That I want to do is delete original file after resizing it and keep only ".thumbnail" and ".size" photo. Is it possible ? Easily ? I think it could be an option in setup.
Thanks for answer.
