Things 3 OmniFocus photo?

Does anyone know if I can attach a photo to a reminder in things 3 or OmniFocus?

You can in OmniFocus.

This isn’t possible in Things, but there’s a good workaround:

The folks at The Sweet Setup are using Bear (as am I, and it works well), but it should work with any similar app that supports URL schemes.

That said, I don’t often have a need to use attachments in my task manager; I’m far more likely to be sending Things a link to an email.
