How to add a static block after product images on product page in Magento 2

1. Create the static block you want to add after the image. When asked to give the block an identifier add something unique this will replace block_indentifier_here in the code below. 
2. Use this code to add the block remembering to change the block identifier and giving the layout update a namespace such as custom.image.after

<referenceContainer name="product.info.media">  
            <block class="Magento\Cms\Block\Block" name="block_namespace_here" after="-" >
                <arguments>
                    <argument name="block_id" xsi:type="string">block_indentifier_here</argument>
                </arguments>
            </block>
</referenceContainer>

Now you just need to style your contents that you’ve added to your CMS block. In my example below I am using an image as a banner but you could just as well inject anything you can put into a static block including widgets, products, code, text, video and more.
