Actually, if you double click a locked image and select "Ok" to the new layer, it'll automatically become unlocked. Also, even if an image is locked, there's nothing keeping you from right clicking and duplicating the image so that you don't need to do all that copy and paste work.

What works best for me is just to right click the original image, select "duplicate layer" and set this second duplicated layer to soft light, mess around with the opacity and then merge the image together.
