How to keep an image static and prevent text from passing an image?

I have a document, and I'm using images as section dividers.

I.e.:

{Title Image}: How to Save Money

{Heading Image}: Step 1

Some text here about the first steps you can take to save money.

{Heading Image 2}: Step 2

Some text here about the second steps you can take to save money.

I am facing this issue: the text wraps around the image instead of making a new page. This issue messes up the whole formatting of the entire document. I want to know how to make it so that the text can't jump past the header.

I.e.:

{Title Image}: How to Save Money

{Heading Image}: Step 1

Some text here about the first steps you can take to save money.

{Heading Image 2}: Step 2

Continuation text here about the first steps you can take to save money. (It went past header 2)

Some text here about the second steps you can take to save money.

How do I format my image or pages document so that this doesn't happen? I want to hit enter at the end of one page and start a new page without it going past the header image.

I.e.:

{Title Image}: How to Save Money

{Heading Image}: Step 1

Some text here about the first steps you can take to save money.

New page to enter text

Another new page to enter text

{Subheading Image}: Step 1b

New page

New page

{Heading Image 2}: Step 2

Some text here about the second steps you can take to save money.

Instead, it does this.

I.e.:

First Step

{Title Image}: How to Save Money

{Heading Image}: Step 1

Some text here about the first steps you can take to save money.

{Subheading Image}: Step 1b

Continuation text here about the first steps you can take to save money. (It went past subheading image)

Stuff about a secondary step 1

{Heading Image 2}: Step 2

Continuation secondary step 1

Some text here about the second steps you can take to save money.

It just creates a mess.

Please help.
