How to make a book with pictures only
Every picture must be aligned and the HTML code must end with a sign or nothing will be visible. If you look carefully at the end of the last row, you see a dot. Remove it and no pictures will be visible. Remove the <DIV> tag before the <IMG> tag and the picture will not show up either. I used the same picture 2 times just for test to see how it looked in game.
Put this HTML inside a book and change the pathes and filename to your own that are stored somewhere at: Data\textures\menus\Book\MySubFolder
<FONT face=1>
<DIV align="center"><IMG src="Book/pek/FR01/1.dds" width=480 height=512>
<DIV align="center"><IMG src="Book/pek/FR01/1.dds" width=480 height=512>.
Note: The line pek/FRO1/1.dds is just a different folder path... for example, if your picture is stored in Data\textures\menus\book\pics, and your file is called thing then it would be:
<FONT face=1>
<DIV align="center"><IMG src="book/pics/thing.dds" width=480 height=512>
Your pictures, which are best saved as 512 * 512 dds, will show up inside the book exactly as you created them and they will not be rescaled nor resized as bookart was in Morrowind, which is good as we don't need to calculate sizes and shapes any longer.
Text and pictures seems not be controllable with the <p> nor the <br> tags so I make text with the Script-Fu logotype texttools at gimp http://www.gimp.org instead.
NB: The problem with <IMG> tags can be avoided. <IMG> tags will disrupt additional coding in a book, even other <IMG> tags. It seems some form of text, or a space after additional coding placed after an <IMG> tag helps stop the disruption. Use books made by Bethesda (such as "The Firmament") as an example of how it is done.
