It's happened again!
Some time ago I was very concerned that an image did not show when converting from ePub to Kindle even though similar images did show. After some discussion it seems that the problem may have been caused by me setting the conversion process to hide fake margins - whatever the reason the image 'came back' and I went on developing the book.
I've recently changed other parts of the ebook, and am using the latest version of calibre, and that same image again does not show in the Kindle file even though though it does show in the original ePub file. Other similar files do show - bigger and smaller, deep color or 255 grays, and different percentages.
The file which does not show is signature.png, which is attached. Also attached are Greenman.png which does show, and SPblurb.png which does show.
All three files have the same markup shown below, except of course that the file names are different, and the widths are different.
<div class="centre">
<img src="images/signature.png" alt="signature"
width="60%" />
</div>
Can anyone explain what I am doing wrong, or what calibre is doing wrong? The image signature.png does show when I generate the Kindle file with the KindlePreviewer.
I have set the calibre setting to default except for the input and output settings, and have used the image dwig provided.
I've removed the signature.png image and replaced it with signature.jpeg from the original source - that is, not from converting the png to jpeg. That doesn't show either.
