Unfortunately, you can't get to both select start image and set the folder to random at the same time. Now that we have file-parameters, you could create your startpage slideshow with parameters instead of filemod. See here the slideshow only example:

You still won't be able to control both startimage AND have random sorting though ...

Like I said, you can either have random, or not-random ... In the case that you use non-random, you can simply drag-n-drop the images into the sorting order that you want. Of course, this means you can also set the first image, which would be the "start image" ...
