Picture book woes

[mjb11800]

! Hi there,
I'm having a hell of a time converting something relatively simple: It's basically just a series of pictures in Jpeg format (a childrens book).. I converted the images into a 16 page .pdf and then ran it through Calibre. The problem is, after the conversion, the pages are all over the place (split into 2, half above, half below).. all I want it each jpeg to be displayed correctly (one per page).
Anyone have any advice? (perhaps the pdf conversion isnt the best idea?)
HUGE thanks in advance!

You got it in 1.
Place your Jpegs on HTML pages and feed the HTML to Calibre
Or
Use Sigil for simple (without resorting to code view) WYSWYG EPUB.
(BTW Word can make some pretty messy/bloated bunch of EPUB code)

You might also take time to review the limitations of some of the alternate devices and formats for limitations before you start (to save spending effort, only to see it ignored by some formats).

zip up all your images, rename the zip file to have a .cbz extension and convert it. calibre will treat it as a comic.

Hi!
Thanks for the advice - Just downloaded Sigil, will have to have a look this evening.

kovidgoyal, I just tried your method and I had an error saying "ValueError: Could not find an ebook inside the archive"
Just to clarify this technique, zip up the file, right click, rename, change to .cbz open in Calibre, and convert?
Am I missing something?
This is the full error message:

calibre, version 0.8.42
ERROR: Conversion Error: <b>Failed</b>: Convert book 1 of 1 (alli pics.cbz)

Many thanks again folks, really, really appreciate it.

You have to enable file extensions in windows explorer to be able to rename to .cbz

Hi there,
Yes, I've had much more success with that technique, thank-you
Just one question, is there a way of keeping the original size of the pictures through the options? I've tried several times now and they always get compressed down fairly small.
Huge thanks again!

Change the output profile to "Tablet" in calibre.
