If you already have one photo online and would like to upgrade to a Gallery Ad, you can do this by ordering a Gallery Upgrade.  There is a reduced price for a couple of weeks after your original order so that you do not overpay.  If you already have a Gallery Ad, you may order Extra Photos to add 2 more photos to your ad (limit 6).

You may also upgrade to a Spotlight Ad from either a single-photo ad or gallery ad for a reduced price within the first 30 days of your original order. Login and click the Order Photos button, scroll down to near the bottom of the Order Options screen until you see the Gallery Upgrade option.
