Android : Hosting the image with the static URL that can be updated everyday. (android studio)

I want my app (android) to load the image from the URL to Imageview. However, I want to be able to update the image everyday. In other word, I am looking the host or sharing site that let me upload picture but allow me to keep the same URL when I'm uploading the new picture. So anyone know any site or service that suit my need?

Much appreciate!

EDIT: I had tried wordpress but it doesn't allow me to specific my picture's URL.
