Choosing a Transparent or Opaque Background
When you move or copy a selection from an image, any pixels in the selection that match the current background color are, by default, transparent; they do not obscure pixels in the target location.
You can switch from a transparent background (the default) to an opaque background, and back again. When you use a selection tool, the Transparent Background and Opaque Background options appear in the Option selector on the Image Editor toolbar (as seen below).

To switch between a transparent and opaque background
In the Image Editor toolbar, click the Option selector, and then click the appropriate background:
Opaque Background (O): Existing image is obscured by all parts of the selection.
Transparent Background (T): Existing image shows through parts of the selection that match the current background color.
- or -
- On the Image menu, select or clear Draw Opaque.
You can change the background color while a selection is already in effect to change which parts of the image are transparent.
