app/views/charles/show.html.erb:13:in `_app_views_charles_show_html_erb__1019061838_19434530_0'
app/controllers/charles_controller.rb:18:in `show'

Answer 1

On line 10, @charle is an instance variable, whereas on line 13 it isn't. Change it to:

<%= image_tag @charle.image_url.to_s %>

And it should work.
