| #Orverwrite the image_tag based on the idea from Designer Wall (http://webdesignerwall.com/tutorials/css3-image-styles) | |
| def image_tag(source, options = {}) | |
| options.symbolize_keys! | |
| if size = options.delete(:size) | |
| options[:width], options[:height] = size.split("x") if size =~ %r{^\d+x\d+$} | |
