threading full page images in between pages

I may have asked this before in a previous post but I cannot find. I have a 330 page indd file which is made up of images and text. I have  material that needs to be added in between some of the pages  and before I attempt to do this I already know I need to have all the text threaded, which mos t is but there are some breaks. Can someone post a quick tut on how to re thread or add threading manually?

Also, I have a few pages that have full page images and are not threaded. I do not want to add anything in between and have to go back and realize images are covering text a real nightmare so I need to know how to thread the images in between so if I have to add any text or pages in the middle of the doc that ALL the images and text will move and not overlap.

for instance lets say page 33 is text only and is threaded to the next text box but that text box is on page 35. On age 34 is a full page image not a part of the thread, if I leave this the way it is it will not flow if I have to add anything as I need the full page image to flow along in sequence with the threaded text follow?

What do I connect the full page images to thread?

thx
