Converting the Background into an ordinary layer

Before you can use the GIF file format’s ability to preserve transparency, you must create some transparency in your image. You’ll do that by removing the white backdrop surrounding the image. To start this process, you’ll first convert the Background layer to a regular layer, because a Background layer is always locked and cannot have any transparency.

1.
Make sure that the 16Start2.psd file is open in ImageReady.

2.
Select the original (left) version of the image in the image window.

3.
Choose Fit on Screen from the Zoom Level menu in the lower left corner of the image window.

4.
Choose Window > Layers to open the Layers palette, and then open the Layers palette menu and choose Layer Options.

5.
Click OK to close the Layer Options dialog box without changing the default settings (including the name, Layer 0). The layer now appears in the Layer palette as Layer 0.
