When you sign into a Picturelife account, you can decide whether or not you want to enable backup of your camera roll to the Picturelife Cloud.
Once you're in the main app, you can always manage or view the status of your camera roll backup. To do this, select the Upload Status sidebar item. From there, you can enable or disable uploads. You can also look at everything in your camera roll and what specifically is in the upload queue.
In both Camera roll and Upload queue, you can change the upload preference for all of your camera roll media, either as a whole or individually. Use the Options menu button to look for new items, upload or ignore everything, or upload or ignore new items. Tap the small icons in the lower right of each thumbnail to adjust upload preferences for that individual media.
