Here is my bibliography of works of fiction and poetry published in 2018 containing embedded photographs. You can see bibliographies for other years underneath the pull-down menu “Photo-Embedded Literature” at the top of Vertigo. I also maintain bibliography that spans 1892 to the present at Library Thing (http://www.librarything.com/catalog/VertigoTwo). If you know of a book that I have not mentioned, please let me know in a comment. My thanks to the many Vertigo readers who have already pointed out books that I had not known about!
Forrest Gander. Be With. NY: New Directions, 2018. Contains a poem sequence called “Littoral Zone,” which consists of six photographs by Michael Flomen, each facing a section of the poem that, at least in part, includes verbal equivalents and/or references to the image.
