Thank you very much mncowboy

, I have wasted hours converting my files to useless formats
I had 56 files so it was not too much of a pain with the editing in Sigil...
But I wish there was a more simple way
The good thing about my converted azw files was that the images adjust themselves very nicely and smoothly to the page view on kindle, the bad thing is that my kindle interprets each file as one book (with one page) and since navigating between books is a pain on kindle 3rd gen, it's not a solution for me.
Thanks again!
