To create a new image, select File > New. Your display should be similar to the screen shown below.
The "New" dialog box appears in the middle of your screen. This dialog box configures setting for your new document. Set the Preset value to "Web". We would like our working logo banner file to be named logo.gif, 700 pixels wide, 100 pixels high (the Preset will automatically change from Web to Custom after you change the width), have 96 ppi resolution (the default), 8 bit RGB color, and have a transparent background (Background Contents).
Modify the "New" dialog box with these settings. It should be similar to the one shown below:
