To replace a photo in your creation, click or tap the photo directly. The “Replace” option will be available in the panel that opens.
On the website 💻, a side panel with various options, including “Replace”, will appear on the left. If you’re working on an album, a pop-up will appear first: click “Advanced editing” to access this option. A new window will then open, allowing you to choose a photo already in your selection or upload a new one.
On the app 📱, an options bar will appear at the bottom of the screen. Swipe it to the right to find “Replace”. You can then select a photo from your existing selection or upload one from your gallery.
