I've worked on a few projects now where spacing below an image or caption is inconstant with text wrap. I've attached two examples from a 600+ page book I'm working on. In the past, I have manually manipulated each photo to ensure there was evening spacing; however, I'm really hoping there is a solution. I've done a lot research.
I group captions and images, then apply wrap to the group. This still doesn't guarantee the same wrap, but it will not be off more than one line in those cases where the size height of the group is not an exact match for a multiple of the leading.
