I mostly use the MDE to get a cover.
Mostly, because sometimes those are not what I want.
When I first started, I documented what was on my shelves and storage bins:
I want the cover that was on my dead tree copy .
I did not need / want high res poster quality.
I frequently use the
Search the Internet PI to find covers
(note size searching can be confused by sources that have whitespace frames included in the images. In that case, the trim: auto trim feature of the MDE cleans that up, but then the actual image may be way smaller)
I also frequently use the Trim, rotate, resize tools built into the book editor.
(remember to pull the new image into the Calibre database. Set cover from the selected format in the MDE)
Another handy tool for those that don't need or want big cover files is the
Resize Cover PI
