One can use Windows, as long as your browser is either Opera, Firefox, or Netscape 8. All of those display embedded images just fine. I generally glance at the thumbnails that IE users still insert, and only if the thumbnail looks absolutely entrancing will I employ one of the laborious work-arounds (discussed in other threads here) to see the enlarged image.
I do wish the thumbnail feature would be fixed, but it's now almost half a year since it first happened, and no fix has been announced. Until it is fixed (if ever), it is indeed a kindness to the rest of us to use embedded images rather than thumbnails.
