A views page as “Output this field as a link” in a block (Drupal)
Images can automatically be made to link to either their node or directly to the image itself using the 'manage display' tab on the content type: admin/structure/types/manage/content_type/display


I would simply make your view an unordered list of teasers and link each image to the file itself if you only want to display the image, or if you would like to have other fields such as a description you could select content and link it out to the node. I am not sure how you have your content type setup but best practice would be to have the fields setup similar to the screenshot below. You would have one image field per photograph and simply use the teaser display mode and image styles to display thumbnails in a listing.
