And what option did you choose? FWIW, I’ve had no problems with using an external image that I pointed to.
I chose both. When I chose "use existing image file", it didn't do anything, it just shows the first page of the ebook as the cover, which obviously I didn't want. When I chose "rasterise first page" it just displayed the "cover" on page 1 as if it were part of the document, which isn't really what I'm after.
And I've tried all three image types, GIF, PNG, and JPEG, in both RGB and CMYK formats, but none of them seem to want to work
Just to be sure, have you updated InDesign to 7.5.2?
What size is the image? I’ve found success with 600x860.
Yep, I've just checked, and I'm on 7.5.2
The image I used was 2:3 (specifically 600x900), as it conforms to the thumbnail that you see in both readers that I'm trying it out on, but I've just tried 600x860 (an RGB JPEG) and that didn't work either
I am having the same issue AndeeDee. Did you ever find a solution?
Weirdly, when I put the ePub on an iPad and opened it in iBook, the cover did actually show up. So I guess it varies from program to program.
I already have this problem and solve it, like this:
First, in ID create a file with one page and put your cover image, don't need anchor it, just put on the size of the page.
2. After export, edit the epub on Sigil or similar program.
Create a css file in text editor like textEdit like this image below:
Insert this css file in folder "Styles". After, in the file of cover change the code (in HTML) to this:
<link href="../Styles/FILE.css" rel="stylesheet" type="text/css" />
<div class="image" id="FILE-COVER.html">
<img alt="COVER-IMAGE.jpg" class="capa" src="../Images/COVER-IMAGE_fmt.jpeg" /></div>
3. Save it. If you wants you can change the background color or remove it.
This will make the cover stay centered and occupying the entire screen.
This operation woks fine in iPad with iBooks and Bluefire.
I hope it helps you
