Hi there
I'm making .epub version of ebooks I created in HTML by uploading the HTML file to Calibre and then adding the cover using the 'Conversion' tool.

When I upload the cover, which is normal book cover dimensions, it gets stretched really wide. How do I stop it from doing this?
Also, what exact pixel sizes does Calibre prefer for book covers?

thanks!
