Kindle paperwhite covers not showing for some news recipes

jhb-812 · 04-28-2025, 06:13 AM

When using the Calibre recipes tool to fetch news, some of the recipes do not show the cover when the device is in Sleep mode, while other recipes show the cover normally. I'm wondering if anyone knows a way to guarantee the covers will show when the device is in Sleep mode.

Not showing: The Economist, The Atlantic, TheAtlantic.com (these covers are screenshots that I manually paste into Calibre each day I fetch news from this source).

Showing normally: The Economist Espresso, Psychology Today.

Note: I thought maybe it was about the size of the photo, but The Atlantic and Psychology Today's covers are almost exactly the same size (PT is slightly larger even) and Psychology Today shows normally while The Atlantic does not show at all.

It has been awhile since I looked into this, but I believe that the cover of the book must be a JPEG image with JFIF and not EXIF metadata for the Kindle lock screen cover feature to work.

No it's not that calibre already automatically takes care of both of those issues.

Perhaps that bypasses the work that calibre does to correct this issue.

Dont see how it could news downloads work via the regular conversion system, the actual download happens in the input plugin the rest of the pipeline is the same. But should be easy to check by inspecting the cover of one of these downloads for EXIF/JFIF

actually i just re-read the OPs post, what does (screenshots i manually paste into calibre) mean? Are you saying you are not using the covers generated by the fetch news process?
