Could this support watermarking?

Looking good so far, just curious if something like this could support automatic watermarking of all images programmatically, as this is a common request from clients.

Thank you!!! 🤗

Definitely, since sharp has it: https://github.com/lovell/sharp/issues/239

Generally we should include pre/post processing callback prop.
