Strange image conversion problem ePub to mobi

Good afternoon all

- The background to this posting is that I have made an ePub book, and know that the XHTML and CSS validate to W3C standards and that the ebook itself validates with ePubCheck.
- The ebook contains several images, two of them black text on white background which show without problem in the original ePub version on my Sony reader, with ADE, and with the calibre viewer.
- But after converting the ebook to mobi with calibre the two images do not show in the mobi version when it is viewed on a Kindle, with the Kindle Previewer, or with the calibre viewer. There is nothing to show that an image is there at all.
- When I converted the ebook to mobi with earlier versions of calibre the two images did show on the Kindle, but I had no need to test them on with the Kindle Previewer or the calibre viewer.
- When I generate the mobi version by opening the ePub version with the Kindle Previewer the images do show on the resultant mobi version. There are other problems, but the images show as expected.
- I have attached the two images.

Is there a way to fix this problem?

I'll see if I can get the publisher's permission to upload the complete ebook if that would help.

You need to open a bug report and attach the epub file. You can mark the report private if the work is copyrighted.

Thanks, Kovid.

I'll try to get the owner's permission, and if unsuccessful will set up a dummy ebook containing the two images.

It is curious that one of the images is a 24bit RGB PNG and the other, SPblurg.png, a 32bit PNG.

If you can't wait for a Calibre fix, I would suggest converting both to 24bit RGB JPEGs like these:

Thanks for your trouble, though I'm not sure why it should make a difference.

It's taken me some time to convert the ebook, and I have tested earlier versions with earlier versions of calibre and the same graphics without any problem. Anyway, nothing ventured nothing gained, I'll try your graphics and see that fixes the problem.

I may have to wait anyway; I've tried to register the bug but as I've mentioned in another can't get through the Launchpad Captcha barrier.

Thanks, Kovid. I'll do that within the next few days.

I had another try at Launchpad last night using MSIE, and had exactly the same result - it refused to accept pairs of words I had selected for simplicity, and which I'm 99.8% sure I entered correctly.

MSIE
That is probably the problem: Really! (I have heard reports that IE does not play well with LP (That's different. Usually I have to use IE for to use features of someones site. USFTC ) ).

Thanks again, Kovid. I've been away for a few days, but please find attached a version of the ePub ebook which I had the image conversion problem.

The only difference between the original file and the attached file is that I have replace the chapter text with dummy text. Everything else is the same.

The signature.image shows when I view the original ePub file but does not show when I view the file converted to mobi.

I've also attached the mobi version.

Yes, I carried on something dreadful in the main calibre forum.

Thanks for your suggestions.

I'm confused. I opened the MOBI file you attached in both the kindle previewer and the calibre ebook viewer and both those images were visible.

I checked it on a Kindle 3 and saw no problems with the images. Both of the two in question displayed fine, both on their pages and when zoomed

I agree with the other posters that tried your files. They seem to work perfectly. The images in question are viewable from the Kindle Previewer and from a Kindle 3. I'm not really sure what the problem is.

Thanks for all your reports. I agree that it works on the Kindle; I'm embarrassed that I did not check it after removing the chapter text.

But I still have the original version with the chapter text in place where the signature does not show. I guess I'll have to put back the chapters one by one to see what happens.

Thanks again.
