html - Rails: Embedding URL within Image Tag -

i have following in html.erb file:

<%= image_tag "logo.jpg", :class => "img-responsive", :href =>"http://www.google.com" %> 

however, not clickable link. assumed :href = > make so. have ideas of making rails image clickable link? tried following logic found on stack overflow post:

<%= link_to image_tag("logo.jpg", :class => "img-responsive"), "http://wwww.google.com" %> 

but makes image smaller , adds odd half circle @ bottom of image. cannot add :style or :class working properly.

anyone have ideas?

not sure if best way, wrap image tag regular anchor tags:

<a href="http://www.google.com">   <%= image_tag "logo.jpg", :class => "img-responsive" %> </a>
