[REQUEST] Allow picking images from external app

[chefexperte]

I think allowing to pick images from external image apps would be great.

All image apps have their own way of sorting albums and images, so it's easier to find a picture with my favorite image app. Adding a button in the upper bar which opens the dialog to select an image would be great.

Maybe something like this here:

I'll have a look in to this, thanks for the suggestion 🙂
