How can I split an image up into multiple layers?

do you know how to make selections in photoshop.

Nope.

Are you talking about just making something like splitting a rectangle into smaller squares?  Or are you trying to imitate a 3d image, by layering the foreground and background?

If you can see the Photoshop toolbar, all you have to do is select the dashed-square tool, make your selection that you want to be a layer, right click inside your select, and select layer via cut.  Then you will have separate layers that still form the original image.

I know you probably will not reward points for this but I would recommend seeking tutorials and learning about 'selections' in photoshop.  I think the 'pen tool' is the most versatile and easy to use to make selections.  Selecting pixels and cutting or copying them onto their own layer is necessary to do what you are seeking.  

worldinchaos, can you have it seperate the image into more than two layers?  If so, how?

Thanks!

sorry but im failing to understand your objective here :)

are you working on a JPEG/TIFF file which is already a full fledge image, in other words flattened and you want to "cut" the images in pieces and have the pieces on different layers?

or you are working on a document in photoshop and you need your objects/pics on different layers so that you can toggle the objects on and off when required?

In order to make multiple layers, just make small selections, create a layer from that selection, and do this multiple times.  If you want to make new, smaller layers from previous 'pieces', then be sure to select the layer you want to cut from in the layer palette.  You can do this an infinite number of times, and have many layers.
You may also use the pen tool, oval tool, or some of the other 'selection' tools in order to create different layer shapes.

Yes SheharyaarSaahil,  I have a full image (JPEG/PNG) and want to decompose this image into many layers, that by themselves don't form the original image, but when they are combined form the original image.

worldinchaos - does this seperate the image into puzzle pieces that I can combine later on or does this take the picture and form layers like I describe above?
