You'll save a lot of room on the page if you switch from centered images to aligning them left or right (I prefer right). That way the text will flow around them like for the TOC.
You can use the Image tool or just handcode it:
(put square brackets around the following, and use the ID of your photo instead of 12345)
img:12345:alignright:small:here is a caption
"As an adolescent I aspired to lasting fame, I craved factual certainty, and I thirsted for a meaningful vision of human life - so I became a scientist. This is like becoming an archbishop so you can meet girls."
