Steps to reproduce the bug

Not entirely sure. I've used the app normally for nearly a year. I have "Show preview images" enabled. I also cleared the cache using Android settings.

I did also disable and re-enable "Show preview images" to attempt to clear the images cache, but that had no effect.

Actual behavior

Very high "user data" usage in Android settings. I do not use the app for podcasts, but my "user data" value is at about 2.5 GB. I assume this is related to preview images being classified as "user data" instead of "cache," but I haven't looked through any code to verify this.

Expected behavior

Clearing cache in Android settings removes all preview images and requires them to be re-downloaded.
