Try:

1. Un-Zipping the .epub into a folder.

2. Find any graphic image files. The book covers and any maps or charts,
as well as any other embedded images.

3. Use a graphic editor, like the free GIMP2, to convert the images into
grayscale black and white images and scale them to fit the display dimensions
of the JBL, at the resolution of the JBL's display.

4. Replace the original image files in the un-zipped folder, with the ones you
have made.

5. Re-Zip the folder into a .zip file.

6. Load the new .zip file into Calibre and convert it into a new .epub ebook.
( Remember to use the "Jetbook 5-inch" output profile.)

Now see how fast it loads.

Luck;
Ken
Thanks Ken. I'll try this experiment when I get a chance.
