I want to add custom image in a invoice pdf. The image to display is from my custom table based on order id. I am able to add the image in pdf using the below code.

}

The issue is:

Invoice with a single item in pdf -> my image is displaying properly
Invoice with multiple items in order -> don't have space in first page. So displaying as
http://i.prntscr.com/CRm-KGvjSimZCFDj2TcLEQ.png

So I have added new page function $page = $this->newPage(); in function insertConditions()

But now my custom image is always showing n the second page. Even if we have space remaining in the first page.

How can I solve this:adding new page only when no remaining space in the first page.
