I’m not sure what you mean by you don’t want to do it that way. Don’t want to do what what way? Do you mean anchoring the art? Or is the art already anchored?
The only way to keep pictures with text is to anchor them (I usually use a hard return on zero leading).
If, by adding the hard return, the art and text is jumping (thus the oveflow symbol), it means that the art is no longer fitting with the text as there is too much text. Normally it would jump to the next page, unless those pages aren’t threaded.
Are you sure all the text frames are threaded?
And the three pages aren’t lost–the text and pictures are still there, they just won’t wit on the page as the page is too full.
It sounds like if you’re adding text (such as that extra hard return), you will need to unanchor that art and reanchor it as a different spot.
I admit it’s frustrating when I have a large book with tons of art and the the book is heavily edited. It makes it a real pain to un-anchor and re-anchor the art. But that’s part of the job, especially when we have to anchor art.
Hopefully David, Ari, or a few of the other experts will chime in.
If we had a small bit of the file to look at, or screenshots showing your pages (with invisibles turned on).
