How do I stop images from jumping around?

Question

When I insert new images on a page above one that's already formatted, it makes all the images and text boxes below go completely haywire.  Literally everything jumps around and looks terrible.  Is there a way to make images stick to a certain spot on the page?  Even when there's plenty of room for a new image or text box, putting something in ruins the whole document and adds a huge amount of reformatting work.  Surely there's a solution to this?  I searched, but I couldn't find anything.  I have a document that was mostly done, but needed me to add more images on the first few pages.  Now the whole document looks cruddy and I foresee hours of work to fix the pages below. 
Whenever I worked in Word, I would do a hard page break to prevent this from happening - that way images and text from one page literally can't jump onto the next page - if more room was needed, instead of ruining the page below it, a new page in between would be created.  But I couldn't find a way to do that in Pages either.

Uncheck Object causes Wrap
It is either on or it is off. If it is on and the object is free floating it of course will push text out of its way, you just have to follow exactly how that is happening and what the consequences are for the surrounding text
Menu > View > Show Invisibles
To see what invisible characters, like spaces, tabs returns etc you have that are being pushed around by the objects with Wrap.
Move with text makes the image/texbox inline which then acts like a very large character in the text.
Inline objects behave just like characters except they are big and so make the line height large and of course they occupy a large space within the line. You can make the whole process more predictable by pasting them on their own line.
