map all image files

[nathanredblur]

Hi
I need to search in all css and jade files all references files that start with '/assets/' and replace it for the cdn url.

img(src='/uploads/images/image1.jpg')
...
img(src='/uploads/images/image999.jpg')

to

img(src='//cdn.my-cdn.com/uploads/images/image1.jpg')
...
img(src='//cdn.my-cdn.com/uploads/images/image999.jpg')

I have this

local2cdn: {
      dist: {
        options: {
          prefix: '//cdn.my-cdn.com',
          maps: [
            {local: '\/assets\/', cdn: '/assets/',  srcType:'image', regex:true}
          ]
        },
        files: [{
          expand: true,
          cwd: '<%= yeoman.dist %>/public/css/',
          src: '*.css',
          dest: '<%= yeoman.dist %>/xx/public/css/'
        },{
          expand: true,
          cwd: '<%= yeoman.dist %>/server/views/',
          src: '{,*/}*.jade',
          dest: '<%= yeoman.dist %>/xx/server/views/'
        }]
      }
    },

How can I do this?
