How to style an image tag in Ruby on Rails

Question

I have an image tag as follows:

    <%= image_tag @user.photo.url(:large) %> 

How could I style a border color to one side of that image in CSS? What html would that produce?

by using "style" option:

<%= image_tag @user.photo.url(:large), :style => "border: 1px solid red" %>
