What ?
I just voted couldn't care less, then noticed your explanation, and now I don't think I voted, for what I thought I had.... see?
Do you mean a small image of cover = short book, and vice versa ?
In which case I couldn't care even less - I am reasonably numerate, and can see how many pages there are in the book.
And I have the rest of my life to read it, long or short, if it interests me.
