Yes, that worked ...but I needed to import from a file first which makes a new unnecessary layer, then I copy the picture from this layer to another layer...I shud have done this with a single layer as I do in photoshop.
I added a layer, then theres no way to add any picture in new layer. If I import from file, it makes a new background .layer. But I want to make a new layer as forground and insert picture in it.
