It depends on what you mean by "pull in the image".
If you mean simply paste an image of a map into a Word document there are many options to do this in MM14. The first is follow the instructions of the MM 14 User Guide to create an image of the map:
1. Click the File tab, click Export, and then click Export as Image.
2. In the Save As Type list, click the image format you want to export.
3. Choose a folder, enter the File name, then click Save.
4. An option dialog is shown where you can define the color resolution, transparency, and size for bitmap files.
Then all you need to do is paste the resulting image into the Word document.
Alternatively, as John suggests you can use the Windows 10 snipping tool to create an image, or if you have a virtual image printer driver you can "print" the map as a JPG or other image format.
And, as Ary suggests, if you export to Word there should be an option in the Word Export dialogue box to include an image of the map on the front page. You can then delete the rest of the exported text if you wish.
If however you want to set up a URL link to a map image this is a little more complicated in MM 14. You can export a static web version of the map and link to that, but there are limited options for formatting this. Bear in mind that if you wish to share the Word file you will have to host the web page on a website; things also get messy if you want to update the map.
If you upgrade to MM 2019 you can export an interactive HTML 5 map which is stored on Mindjet's servers and so is easily accessible if you share the map. The exported map can also be easily updated.
HTML 5 map export is a wonderful feature, and one of many reasons to upgrade to MM 2019.
Unfortunately you would have to pay full price as you're coming from MM 14. The upgrade to MM 2019 is only available if you have MM 2017 or 2018, and costs around 50% of the full price. If you get the latest version and sign up for the software assurance program, which costs around 20% of the full price annually, you qualify for free updates.
