Pen's Nest

Thanks for taking a look! This is what puzzles me - I used the Direct link, and there were several images in the post I was composing (had a disaster with Safari this morning and had to force quit, so I don't know if that draft will have saved), but none would show in the Preview. I'm sure I've had this same problem before, and can't remember whether I solved it by simply posting the thing anyway. But it's definitely not showing when I try to preview the post, and I'm not getting any messages about bad html either. :-(
