What do you mean by cut the edges? Use the selection tool and "cut" menu option. Paste into a new image document and save.

Look into using bezier curves for the curved edges part.

I hope this quick tutorial will solve your problem.

  1. Create new image at the correct size for you.

  4. Now fill this layer using the paint bucket. Use the color white.
  5. Next right click on the shape icon and select rounded rectangle.
  6. Set the radius of the corner to 25px.

  11. Hold down control and drag two marquees out (one at a time)over the corners that you do not which to be rounded.

  13. Then hit “delete” on your keyboard. Then hit “ctrl+D” on your keyboard.
  14. Now, right click on your layer with the rounded rectangle on it in the layer palette and select “delete”. Then select yes in the dialog box.

Thats the image finished, now all you need to do is select "save for web" in the file menu. Here's how mine turned out:
