Dimensions::Rails

<%= image_tag 'logo.png' %>

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

It uses dimensions by @sstephenson to automatically add size attributes to image tags, which speeds browser rendering.

How does this improve browser rendering?

See: https://developers.google.com/speed/docs/best-practices/rendering#SpecifyImageDimensions

Installation

Add this line to your application's Gemfile:

gem 'dimensions-rails'

Usage

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.
