Views slideshow from single node
In the views image field settings, under Multiple Field Settings, there is checkbox for "Display All Values in the Same Row" which is checked by default.  If you uncheck this box it will place each image in a new row and it will work as you require.  I know views has had this feature since at least version 2, but it might be called something slightly different in older versions.

I like doing it this way for simple slideshows, I can rearrange all of the images on one node/edit page. But for more complex slideshows, like where each image links somewhere or has alternate text, your best bet is probably still to use one node per row.
