Your cover image is what people see when you share your collection, or it appears in your profile. Your background image won't appear within the app, but will appear if your collection is viewed on a desktop on the web.
To change the cover and background images of your collection:
- Open your collection from the home tab
- Click the pencil icon (edit) at the top of the screen
- Click the camera icon on the image you want to change
- You can then Choose a new image (upload from your phone), Choose an Unsplash Image (select from a royalty-free stock photo library), Reposition your image or Delete it.
- Once you've made your selection, click 'Save' at the top of the screen.
See the screenshot below to see the camera icons on the images, in edit collection mode.
