I don't need code or stuff, so don't waste your precious time on that, just some general hints where and how you would store the pictures online, and how android can download the pictures easily.

Take a look at the Glide or Picasso libraries. Those are super easy to use for thread-safe downloading of images. If you want to upload a dedicated databse, you'll have to set one up. Some common ones are Amazon, Google, etc. There are tons. Have a look at this answer. In this answer Picasso library is used to handle image download. Picasso gets rid of a lot of coding and testing to handle image download. In a project that I am working on, we use Amazon S3 to store our pictures, it's very reliable and is one of the goto solutions right now.

From what I heard Snapchat and some other big firms use S3 to store their picture! It's also very cheap, plus I believe they have free hosting to a certain degree.

This is their API guide for android. We use a service called File Picker to handle upload and download from amazonS3, it reduces a lot of work, but I don't think it's a free service. You can use Picasso for downloading images from network in Android.

For storing images Amazon S3 or Google cloud storage can be your options. Not sure if downloading packages is better than downloading individual pictures archiving won't save you much space.

As for your question, you can make some kind of API you will query from your app, even a flat file hosted somewhere with changing content would work.
