Fix #153 Cover image doesn't show up with epub in iBooks

[clemlatz]

iBooks needs the following meta tag:

<meta name="cover" content="image.cover.png" />

in content.opf in order to display the cover.

Fixes #153

Shouldn't that point at img/cover.png instead?

[clemlatz]

You're absolutely right. I fixed that.

Thanks. Merged. The epub on the website is in the process of being rebuilt.

I still see the issue when downloading the ePub from the website and load it into iBooks.

[marijnh]

Is the meta tag there when you unzip the book? It should be. If it doesn't help, the problem diagnosis may have been wrong in the first place?

[esparkman]

I'll verify. One sec.

Line 75:     <item id="image.cover.png" href="img/cover.png" media-type="image/png"/>

[marijnh]

Could you clarify?

[esparkman]

That is on Line 75 of the content.opf. When I manually pulled and compiled the file it worked just fine.

[clemlatz]

My bad. I think I was right in the first place. Attribute name value should be the id of the image as defined in the manifest item tag and not the image path, so:

<meta name="cover" content="image.cover.png" />

was indeed correct.
