In reply to Simon.

Thanks Simon. Sorry I didn't respond sooner and it looks like Paul has already given you some help.

I like the rag. I would rather the straight line of the caption match the straight line of the bottom edge of the image above.

I think it makes it clearer the caption goes with the image above instead of below. Of course you could also use space to show which goes with which.

I assume you were able to get the captions aligned how you like.
