Nook Color Side Loaded Thumbnails

harrybosch5150 · 05-21-2012, 07:00 AM

I have an issue where my Nook Colors sideloaded books remember the old cover thumbnail.
For example:
I side load a book via USB.
add book to a shelf.
I look at book on a shelf, the cover is Image A.
I delete the book off the Nook.
I find a cover I want (Image B) off the internet.
I use 7-Zip to replace Image A with Image B in the Image folder of the ePub.
I open the ePub using Sigil and make sure that Image B is check as cover in schematic.
Save ePub.
Copy ePub back to Nook via USB.
Add book to shelf
Still has old cover as thumbnail????

The nook keeps a cache of thumbnails for fast display. When you delete the book from the nook (if you do it via the PC), make sure you unmount the nook and let it refresh the library.

I have not tried changing covers, but I have updated books that did not have a cover (which I added via Sigil, similar to what you do), and following these steps it worked for me.
