A Then & Now message is two photos posted in one message, with an older photo shown alongside a newer photo for comparison. For example, a Wedding photo alongside an Anniversary Photo. You have the option of vertical alignment or horizontal alignment of the Then & Now photos as well as photo-cropping features before you post.
To add a Then & Now message, tap + to add a post and tap ‘Then & Now’. Select the desired alignment. Tap ‘Upload Image’ and select a ‘Then’ photo. Crop and rotate as desired. Tap ‘Upload Image’ again and select a ‘Now’ photo. Then enter a caption if desired and click ‘Post’.
