Question

This code in the ERB only displays one image. I thought it would be a simple fix but I’ve scoured google trying to find it. Maybe I’m just forgetting something

<%=
image_tag ruby.png
image_tag ruby.png %>

Answer 1

<%= %> prints the result of the code inside it, not all of it. If you want to display two images, you can do

<%= image_tag('ruby.png') %>
<%= image_tag('ruby.png') %>

or

<%= image_tag('ruby.png') << image_tag('ruby.png') %>

or

<%
  concat(image_tag('ruby.png'))
  concat(image_tag('ruby.png'))
%>
