When you open these folders you have option of choosing an action to run.

To run an action select it in the actions palette and then press the triangle ‘run' button in the middle bottom of the palette. If you choose ‘molten lead' for example it will run through all the steps involved (previously ‘recorded') to create a molten lead effect. You can view the results in the layers palette. Usually running a default action will create more snapshots in the history palette.

You can choose many different Actions to run after you've loaded the folders from the palette menu. Try loading and then running some of these.

If you open an effect folder you can see the detailed commands of the actions which makeup everything that is ‘run' within Photoshop to complete that action.

Note how it creates this effect automatically (when you try it)? All you have to do is ‘run' the action by pressing ‘play' on the actions palette.

It's put a layer above the layer you were on using Screen blending mode.

In this image you can see that I've made some custom adjustment layers. These are very powerful. I cover them in-depth in the Basic Photoshop DVD Training program including tons of other educational tutorials.

If you want to make a new document with the same image dimensions, just select the background layer. Select All.

Edit: Copy and then File: New and then Edit: Paste to put the other background image onto this one.

The easiest way to do this is just Image: Duplicate (if you only have a few layers) and then drag other layers to the trash. It's good to know many ways of doing things; Photoshop is filled with these. There are often many ways to come up with the same results. It's up to you to figure out what's best to do for you in each case once you have the level of understanding.

Anyways, I told you actions were easy to run. Just experiment around with them. They're not that hard to record your own actions (set of commands).  Get my Basic Photoshop training here for less than $50.
