Think of layers in a multi-layered image as representing a stack of transparent sheets placed one on top of the other. Image elements on lower layers will be obscured by elements contained in layers higher in the stack if the element is in the corresponding area. For an in-depth discussion on this concept, please visit the Working with Layers section.
A new image is always created with a single layer named "Background". All images must have at least one layer.

The Active Layer
There is always one active layer. It can be identified by the highlighting in the

Only one layer may have the active layer status at any time.

Layers can have their own blending mode and opacity settings. These are applied to every pixel in the layer.
Other layer options include whether a layer is currently visible or invisible (hidden).
Layer Window Icons
This adds a new, completely transparent layer to the image immediately above the active layer. The new layer will be given a generic name "Layer X" by default. X denotes the layer number - hence it is always a unique identifier.
New layers are filled with transparent black pixels (i.e. ARGB #00000000).
It is possible (and highly recommended) to change the default name to accurately reflect the contents of the layer (see Layer Properties below).
This deletes the active layer from the image. As all images must have at least one layer, the last remaining layer cannot be deleted.
This duplicates the active layer, including its contents and attributes. The new layer will be named uniquely following the pattern described above (Add New Layer).
Merge Layer Down
Takes the active layer and combines or merges it into the layer immediately below it in the
