Did not get if you are looking for Open as Layers in Photoshop or Open as Layers in Photoshop Elements?
Open as Layers in Photoshop Elements would not be available as an option under Edit in because Photoshop Elements has been added as an external editor.
You can access open as layers in Photoshop but you need to make sure you should have Photoshop installed for that.
Let us know if you need any further assistance.
Yes Im looking to open as layers in Photoshop Elements. Elements is the only version of Photoshop I currently own.
Do I need to change my external editor?
That is the expected behaviour.
Open as layers or smart object is available only for the default external editor which is Photoshop.
This feature would not be available for Photoshop Elements.
Only option with Elements is to Open the images separately, then combine them into layers in Elements by a drag & drop method (Move tool?).
