image size reduced

Gregg Bell · 11-07-2018, 04:00 PM

Hi Sigil friends! I noticed on my Kindle ereader that some of the book cover images in the backmatter of my ebooks were about a third of the size they should be. The ones that looked normal looked like screenshot 75. The ones that looked reduced look like screenshot 74. What's up with that? Should the images in the backmatter (because I noticed that when I first open a cover in Sigil that the width and height stuff are automatically there) always be like the example in screenshot 75?

I just copy and paste these images from older ebooks of mine, so I don't know how it's supposed to work.

Thanks.

I've been experimenting and it seems to me that my image size stays the right size when the width and height attributes are specified after I turn the .epub into a .mobi. However, and this is speculation, after I upload that selfsame .mobi to Kindle Direct Publishing, and it does its processing, then the file with the width and height specified is reduced. (And the flipside, again this is speculation, is that the image without the height and width specified does not get reduced.)

I admit to not knowing a thing about image sizing for Kindlebooks, Greg. Perhaps the Kindle Formats forum might be a better place to ask about image-sizing best practices in html/epub source that will be converted to a Kindlebook (and any subsequent KDP alterations)? It's not really a Sigil-specific matter at all.

Thanks a lot, Diap. You're right. And I found some answers talking to KDP so I'm good now.

When I click that, I get a 'No valid thread specified" message?

Well that was extremely weird.

The links should be fixed, now. Thanks for letting me know.
