I have researched the internet for finding solutions to the 2 problems: not to split images into several pages ('nobreak') and how to display the pictures in their original resolution, but haven't found any convincing solution. I have also uploaded a detailed PDF showing the settings I used with Calibre. I tried to also upload the cbz file but it seems this forum doesn't accept uploading cbz files? Anyway it is only 12 pictures in the size of 1536 pixels by 2048 pixels. Please see one attached public domain comic as example the epub result. I have the feeling that many comic lovers dislike the whole idea of epub but I really would like to try to produce an acceptable epub version of comics since it is the only way to be able to distribute them on Amazon and iTunes for example. Very important is also that the pages should not 'split' or 'break' into several pages. With smaller screen resolution e-readers the pages (images) should also show up in their full resolution so that the reader will need to scroll to see the whole page. Only like this it is possible to effectively read the texts in the images.

I would like the pages/images to always show up in the original image resolution (in this case 1536 pixels by 2048 pixels) independently of the e-readers screen resolution. I am trying to convert some Cbz or Cbr comics into Epub with Calibre and I am facing one problem: with the converted Epub the comic pages (= pictures) do not show up in full scale on the e-readers, even though the resolution of my comic pictures are very big (1536 pixels by 2048 pixels).
