bug: Cover not found inside EPUB file #769
Description
I unzipped two books to check sources, one displays the cover:
<manifest>
<item href="xhtml/cover.xhtml" id="cover" media-type="application/xhtml+xml" properties="calibre:title-page"/>
<item href="xhtml/title.xhtml" id="title" media-type="application/xhtml+xml"/>
<item href="xhtml/toc.xhtml" id="html-toc" media-type="application/xhtml+xml"/>
<item href="xhtml/dedication.xhtml" id="dedication" media-type="application/xhtml+xml"/>
<item href="xhtml/chapter001.xhtml" id="chapter001" media-type="application/xhtml+xml"/>
The other doesn't display the cover:
<manifest>
<item href="toc.ncx" id="ncx" media-type="text/xml"/>
<item href="page-template.xpgt" id="pt" media-type="application/vnd.adobe-page-template+xml"/>
<item href="9780061748998_cover.html" id="cover-page" media-type="application/xhtml+xml"/>
<item href="9780061748998_title.html" id="x_9780061748998_01" media-type="application/xhtml+xml"/>
<item href="9780061748998_dedication.html" id="x_9780061748998_02" media-type="application/xhtml+xml"/>
However, KOReader and online readers do display the cover. Is the difference in the id or something else? If that's not the case, let me know and I'll check for more.
