Are your digital images scattered all over? Organize them all by logging on to me.com and uploading everything to create a gallery that your friends and family cannot only view, but add to. For memories on the go, there’s the new MobileMe Gallery app for iPhone or iPod touch. Busy moms will love this app, says Ben Long, author of Complete Digital Photography. “Now moms can easily display up-to-the minute shots of their family, vacation, or day-to-day life,” he says.  With simplicity in mind, the app combines picture taking and management in one device (one-year subscription, single user, $99 from Apple).
