I can’t use a photo as a cover image, why not?
We have a minimum size for the cover photos, they must be at least 1920px wide for the Desktop Cover Photo and 1080px high for the Mobile Cover Photo. If you are receiving an error that your image is too small then you’ll have to upload a higher quality image instead. Any photo taken on a modern camera or smartphone will be plenty large enough.
The Desktop Cover Photo must be a horizontal image and the optional Mobile Cover Photo must be vertical.
