On Barnes & Noble Nookbooks, I tried to import the book cover I designed on openoffice draw and used successfully on amazon.com, but received an error msg saying that the cover must be at least 750 px on the long edge (it's got to be at least that!). I reimported the photo (taken on my iPhone 5) after exporting it and increasing the file size, but got the same result. Any ideas what's wrong here? Also, there's a peach-colored wash behind the subtitle that I need to eliminate, but can't find a way to do that. When I put the cover together, I started by importing the picture, then selected the T tool, but it wouldn't work over the photo, so I had to use it in the blank space to the left, write the title, etc., there, move it to the right with the right cursor, and then use Modify>Arrange>Bring to front to set it properly. I tried to upload the cover image here, but don't know how to do it.
Tx,
