CREATING YOUR OWN CUSTOM NEW DOCUMENT PRESETS
If you're creating new documents and find yourself using the same new document sizes fairly often (for example, let's say that you wind up creating a new document that's 7" wide by 5" tall, at a resolution of 225, in CMYK mode), you can make that a preset in the New dialog of Photoshop CS (technically, you could do this in Photoshop 7 by hacking a text document, but it was a bit of a pain, and most people didn't do it). To create your own presets, just go under the File menu, chose New, then in the New dialog, enter your favorite settings, then press the Save Preset button. A dialog will appear where you can name your preset, and when you click OK, that preset will be saved to the New dialog Preset menu near the top of the list.
