Epsilon - Portrait images

Is there a way to show listing images in portrait mode without adding background?

Try best crop option in media settings.

I tried that. But it's not sufficient.

Is there a way to use an editor like it is for the Profile Picture in the Public Profile?

Public profile image is taken from user profile.

Yes, of course I understand this. But with the user profile image there's an editor (see screenshot) where you can set the cropping yourself which isn't there at the other image uploads.

So, is it possible to use the same editor for the other images, on listings, business profiles, etc.?

This is only available for profile picture upload.
