I'm trying to add captions to my images as well, but your suggestion above isn't working. It puts the text in the ALT field but what I really need to do is something like this:
This is a photo caption
for this photo.
Any ideas on how I might do that? The photo and caption are generally left- or right-aligned within the body of the article that we're going to be building in CE. The rest of the text will flow around the photo and caption.
