Split a scanned photo across multiple pages (with a predifined splitting point)

I am a relative (La)TeX newbie! I want to split an A4 scanned image across two pages! Is there a package to achieve this or is it possible to do this manually so that to be able to define the exact splitting point?

Thank you Yiannis for your reply! My photos are normal A4 pages from an old text book. So lets say that I want to place some scanned page at some line of the current A4 text and downwards. So it is very likely to have to properly split the photo (let say 1/3 of A4 from the top where there is space and no text). So I would like a command(with the splitting point as a parameter) to perfectly split the scanned page. –  kornaros Feb 20 '12 at 13:39
Best to experiment with a real image and text page can you post a scan or see if you can find a link to google books for the textbook? I am not sure if understand you correctly. The image is A4, so you will only display 2/3 of the picture? How about the cropped part? –  Yiannis Lazarides Feb 20 '12 at 14:45
I 'll try to post one. But fist let me make an example for clarify myself. I write some comments about history then I insert some A4 scanned page from an old book, then I make some new comments and then again I insert a new A4 scanned page and put some new comments...e.t.c. So I need a package and/or a command mixing text and scanned pages in a natural way (i.e without loss of information when there is a need to split some scanned pages) –  kornaros Feb 20 '12 at 19:52

You haven't provided any specific details as to the image and page layout so I will describe a general technique that I use here. You can either split the image into two to achieve a centerfold or you can hide a portion of it, as is shown in the two images below, which I had on my hardisk from this answer.

Here is the MWE. You can use \hspace to move images left or right. If you have a single image, you let it overflow on the right (it will not show if it goes past the page) and on the next page, you insert it at the same position, but now with an \hspace*{-\textwidth} to pull it left. This way you do not need to slice the image before hand. If you care to explain in more detail as to the layout you want to achieve, I will extend the example and code. You should also have a look at LaTeX3 xcoffins.

Simpler images and code is possible, as shown below.

\minipage{\textwidth}
\includegraphics[height=\textheight]{./graphics/firesidecomfort}
\endminipage

\hspace*{-1\textwidth}\minipage[t]{\textwidth}\includegraphics[height=\textheight]{./graphics/firesidecomfort}
\endminipage


Since we size the image on the \textheight the image overflows to the right. Then the only thing we need to do on the following page is to pull it by \textwidth. Amazingly simple and powerful.
