Actually it may possible to have it; but it would involve hacking the software.
Or having to manually add each book to one great "book" for indexing.
You could just try doing hyperlinks with an .html
And each hyperlink would be an image, which leads to the actual book.
That way you can browse through an index where you only see the books cover.
But a nice standardization of the image size format would be good, though.
Let's say that a 3x3 grid would work ok; so max width =150; and max height = 250 (150*250).
I "randomly" picked 9 book covers, when all were adjusted to 150 width, every each of them would have a height less that 250!
Kindle screen is 600x800:
3*150 = 350
3*250 = 750
Leaving 150 width for margins and 50 heaight for header and footer.
As an example of what it could look like:
Not bad, uh?
EDIT: I think we should ask the "Developer corner" in Kindle subforum.
Im 90% sure the image is sized as "Real size"; maybe a lilttle bit bigger. [im on a 1280*1024 screen]
EDIT N°2:
@HarryT:
NOt really; if the idea proposed works; it would be very similar.
Kindle (or at least my K3) shows 10 books per page. With this 3*3 grid you get 9 books a page.
