# This simple program takes a bunch of images and creates a sprite image along with the corrosponding
# css. It also generates the datauri css. So, we can serve performance optimized CSS depending on the 
# Browsers.
#
# Browsers which do not support datauri, like IE7 and below get the sprite image and the sprite css.
# Browsers which support datauri, get the datauri.css
# 
# Usage:

require 'uri_validator'

Note that this validation runs both after the file is uploaded and after CarrierWave has processed the image. If your base uploader includes a filter to resize the image then the validation will be run against the resized image, not the original one that was uploaded. If this causes a problem for you, then you should avoid using a resizing filter on the base uploader and put any specific size requirements in a version instead.

So instead of this:

require 'carrierwave/processing/mini_magick'
