In GIMP I created a cover jpeg, and three other jpegs, saved them, inserted them in LibreOffice Writer, saved the file as html, then fed into Calibre. Here are the sizes of the initial jpegs, and the final sizes in the Calibre eBook. (Laptop screen: 1366 pix wide, 100ppi.)

1) 1700 pix wide (100ppi) ----- 3.35” on screen (335 laptop pixels)
2) 350 pix wide (100ppi) ----- 3.3” on screen (330 laptop pixels)
3) 700 pix wide (100ppi) ----- 6.3” on screen (630 laptop pixels)
4) 700 pix wide (200ppi) -----6.3” on screen (630 laptop pixels)

Why does No. 3 (700 wide graphic) display wider than No. 1 (1700 wide cover)?
