Stacks presentation - how to change?

I'm using OS X Leopard on a MacBook. When I call up my Documents stack, it just gives me a list of documents in the stack. When I call up my Downloads stack, it gives me the document icon of the first page of the document, which I prefer.

How can I changed the Documents stack to display the icons of documents instead of a list? TIA.

I'm going to assume you want to use grid mode instead of list mode. If that's the case, then right click on the Documents stack and select Grid under "View contents as"

Stacks

Thank you!
