What would be the setting that determines the default length that a photo appears on the timeframe? I'm dropping a big bunch at once and don't want to take time shortening the duration of each one at a time. Can I adjust the default?

If you have Movie Studio Platinum 12 or later, you might want to look into purchasing the VASST Still Motion plug-in for $9.95. It will save you lots of time and allow you to change the length of all of the images anytime you want with a single click. You can even sync them to the duration of your music.
In the interest of full disclosure: I work for VASST and wrote Still Motion ;-)
