To select your wedding album photos, you must create and share a favorites folder of the images you'd like to use:

From a single image preview: Click the "add to favorites" link above the image
From a gallery of thumbnails: Click the heart left of the images you want to select

Once you have assembled your selection, navigate to the gallery (link in top left)

From the favorites gallery, click the "Send to" button in the top left and fill out the form that pops up, and then click the "share" button.

Your selections have been sent to the photographer and an album layout will be delivered to you in 30 days for your review.
