No problem. It's a thread resurrrection anyhow.
And it sounded to me (or rather, to the geek in me) like the artwork was not anchored to the text, but to the page itself. Hence my question regarding styles and layout constraints.
And that's why an image should be attached to the paragraph that explains it and not a position on a page.
Imagine: An image of roughly 1/4 page, is anchored to the text, and placed in the lower right hand corner of the right hand page in the spread, and the image is oriented so that it faces towards the spine, the center of the open spread.
Now imagine the font size is changed just enough to push that image down
one line and the image moves to the next page.
Now you have a roughly 1/4 page sized hole at the bottom of the previous page, and the image is moved to the upper left hand corner of the left hand page in the next spread, and the image is oriented so that it is facing somewhere to the upper left of the upper left corner of the page.
Not good.
Forgot to mention: If there happens to be an image already on the next page, now you have two images on the same page.
Smooth.
Generally speaking you don't want to anchor images to the text, because there are limits to where images should appear on the page-- in the corners, in the center, etc. You want to be cognizant of how and why text is interrupted by an image.
Clean layout is not a process well-served by automation.
