With regard the book covers, have you tried obtaining them through the 'edit metadata' tab?
In this tab click on 'download cover' this will start a web search and may give you different size covers (pixels) for example one of my books is: 500 x 762 pixels, but by doing a search I can get the following sizes: 575 x 872 and 325 x 480, now this may not be the answer but it may be worth trying.
Failing that you should consider emailing the developer to see if he can help you.
