For digital comics, I’d like to be able to read them without having to get them copied on my local device as they tend to be fairly large and a few comics add up to a lot of lost SD Card space very quickly. Is there a way I can put them into Plex and read them from my Tablet over the wireless?
not per default

Or install a full-grown ebook server alongside plex. Calibre springs to mind.
