How do I stop an icon from looping/replaying?

All icons are set to seamlessly loop. To change this:

ps-animation-looping

When you’re ready to save, select “Save for Web and Devices” from the File menu. Select GIF, and the desired number of colors. Be sure to check the Transparency, Matte, and Animation Options at the bottom of the dialog. The Animation Options should now indicate the change you made above. Click “Save” and save the file as a new name.
