Topic: Picture Order Using Picassa

I use Picassa to create my Simpleviewer galleries.

Apparently Picassa and Simpleviewer generate galleries with the images that have the earliest date first.    I would like to have the latest pictures displayed first.. this way you will alway see the newest images first.

How can this be achieved?

Tried a search but only found something pertaining to PHP.  I don't use PHP so I'm trusting you guys for a solution.
