Node View, flash upload

Is there a way to change the view of the node preview (in my case it's one big picture, for example at the Home site)? I would like to have instead of one picture for example 9 little pictures (like at the full node view). Is that possible and how/where can I change this?

My secound question is: Is it possible to integrate a flash upload? I like to have an upload, where I can select more than one picture at once without x-time clicking "browse"? Is there anything like that integreated or can I solve this with an other module?

Thanks
