Build Status

<%= image_tag 'logo.png' %>
<img src="/assets/logo.png" width="230" height="80">

It uses dimensions by @sstephenson to add automatic images size and improve browser rendering.

How this improves browser rendering?



Add this line to your application's Gemfile:

gem 'dimensions-rails'


Just use the image_tag rails helper as usual, the :size options will be magically added by dimensions-rails elves!

If for any reason you need to disable dimensions-rails just pass :dimensions => false to image_tag.
