What I want is normal posts have featured image as header
then I have variable height headers for the front or posts w/o featured image.
Then I want a static front page and separate posts page. I want a slideshow like modularity-lite on the front page. Now I've worked out it's not possible already and it must be on the posts page so that's out.
Failing that I want the front page to have a large header, really big, and some intro text down bottom like a proper business site (vs a blog).
But that means only front page can use that header, ie it should really be a featured image but they don't have variable sizes.
I have looked at Oxygen and really like it, except for 3 col and also featured image on posts page (and deletes any floating image I had on post)
Maybe I should look at it from another way. I need a businesslike front page. Menu for blog posts, and other pages.
Front page should have a really big image on it.
