I suspect the issue is in how you are constructing this link, and how you have directed your controller to respond to a "format: js" request. When you say "remote: true", then your controller must be set up to respond with your desired layout in the format.js section of the respond_to block.

In the past, I have done these without using the remote: true thing at all. I suspect you can remove it as well. Try the following:

# posts_controller.rb
# add a new method next to show()

def modal
@post = Post.find params[:id]
end

# views/posts/modal.html.erb

<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
<h4><%= @post.title %></h4>
</div>
<div class="modal-body">
<%= @post.whatever_else_you_want_to_render %>
</div>
<div class="modal-footer">
<button class="btn btn-default" data-dismiss="modal">Close</button>
</div>

(be sure to put whatever actual erb you want to use in your modal-body section)

# routes.rb

resources :posts do
member do
get :modal
end
end

Now to link to it, you will have a new modal_post_path() helper to play with, so your link would look like this:

<%= link_to image_tag(post.photo.url(:medium), style: 'height: 300px;
width: 500px;'), modal_post_path(post), data: {:toggle => 'modal', :target =>
'#reusable_modal'}, lazy: true %>

See how that goes for you.
