You don’t need to rent a server, can use a public photo hosting (like tinypic, or imageshack), just use direct link, and check if, and when they will delete the pic. If you app is already in play store, you can get url to the logo uploaded there (the 512x logo on the top left). It works with this link, and since you will probably be linking to playstore anyways, they should not have objections (But you better check).
