Here is the simplest way I know of to make something, like an image, a link to content in a Drupal view. It's useful for making things like a grid of images that need to link to content.

1. Add a Content: ID field and exclude it from display. Make sure it is on top of the list of fields.
2. Add a Content: Image field.
3. Click on the Content: Image field to edit it.
4. Click Rewrite results and select "Output this field as a custom link”.
5. Set the path to /node/{{ nid }}.
