Open a Finder window, and in the left FAVORITES panel, click Applications. Look for either of the Adobe icons shown below.

If you have one of these, launch it, and click on the Help menu to check for updates. You want to keep it updated. If you have neither, then you will have to download and install it from the official Adobe site. The default PDF reader will remain Preview. The Export to PDF option in Pages gets you to a PDF. Right-click on that PDF, and from the pop-up menu, choose Open with Acrobat Reader. There are two Reader icons that represent the new (DC) reader, and the older version.
You cannot suppress the printing of images in a PDF — not in Preview, nor Adobe Acrobat Reader. PDFs are in a final format, and only PDF Editors can revise the content. Pages is not a PDF editor, though you can drag/drop a PDF page onto it and use it like a scalable image object.
If you are on Mountain Lion (OS X 10.8.5 or later), and have the free LibreOffice, you can open a PDF (launch LibreOffice and use the Open… menu item) with your pictures in it. If it is a multi-page PDF, then in the LibreOffice View menu, select Page Pane, to enable thumbnails. Click on each picture to select it, and press delete. Your document formatting does not change, but will just have holes where the pictures were located. Don't save it, but instead, export as PDF (use a different name for the new PDF). Now, you can print the resultant PDF without pictures.
Once you click the LibreOffice download button, it will switch to a donation page. Just drum your fingers for a couple seconds, and it will then start the download without a donation. Inside the LibreOffice installer, just drag it onto the Applications folder alias included in the installer. This will install everything beneath one icon in your Applications folder. Right-click on the LibreOffice icon, and choose Open. At the pop-up, choose open again. You only need to do this once. Afterwards, LibreOffice will launch with a double-click, and it is also in your Launchpad items.
