Link to a referenced entity
ER fields store only the ID of the referenced entity.
Pulling in other information about the referenced entity usually involves adding Relationships, but some details can also be shown through the Formatter Field setting.
Set Formatter to Entity ID and Rewrite
Without adding the Relationship edit the ER field, set the Formatter to Entity ID, then under Rewrite results turn on Override the output of this field with custom text and enter something like this into the Text field:
&lt;a href=&quot;/node/{{ field_myreferencetoB__target_id }}&quot;&gt;{{ field_myImagefield }}&lt;/a&gt;
Check the correct tokens under Replacement patterns a bit lower under the Text field.
You can also achieve similar result with Output this field as a custom link which has more options for the link if you need them. In this case the Text field will only hold the image token and this option will contrast the anchor HTML.
This approach is helpful when you have a multivalue field it will be possible to show all values in the same row, while using a Relationships usually splits them into separate rows and it requires more steps to aggregate them.
Use the ER Relationship
If you add the ER Relation ship you will be able to add the Link to content field and make it use that Relationship to show the link to the Referenced entity instead of link to the original row entity.
You may want to use the Output the URL as text option to make the token output more predictable.
Now you have the referenced entity link in your Views you can use it to Rewrite other fields.
