I am editing this post:
The last 2 photos on the blog need to have captions inserted in the edit image dialog - right now they are just a line of text I typed in below the photo - they look different from the others because of this.
Have them try to either copy and paste in the image attribution - it's listed below the image - or type it in - it won't save.
If I paste in a photo rather than upload it, the image will show, but I can't assign a caption.
Otherwise, if I try to start from scratch and delete the photo and either reload from my laptop or reload it from the gallery within the add media interface, I get the gray box with the placeholder error - looks like this - it shows the descriptor and the caption, but no viewable image.
btw: seems also that [caption] tags somehow get occasionally disrupted and become usual divs which breaks all markup
