title: What is the proper image size for an ePub cover page?
body: <p>I am using the most excellent PHP library <a href="http://www.phpclasses.org/package/6115-PHP-Create-ebook-in-EPUB-format-for-ex-Apple-iPad.html" rel="nofollow" title="ePub.php">ePub</a> to on-the-fly create digital books from HTML stored in my database.</p>
  
  <p>As these are part of a collection, I am including a cover image for every book.  Everything works fine in the code but depending upon the device/software interpreting the ePub, the image may get cut off.  I have seen 600x800 pixels as a recommended size, but it still cuts it off (for example in Aldiko in Android).  Is there a standard size that is recommended in the documentation?  </p>
  
  <p>Honestly, I would love a good and readable recommendation for documentation of the ePub format.</p>
