 3. Supports cropping of ONE attachment per model. Can be directly applied on original attachment if no versions exists.

 4. Supports cropping of MULTIPLE versions of one attachment per model.
 5. In form helpers, by default *original image* is rendered. To render a specific version for cropping pass `version` option. For example:
 
-         <%= f.cropbox :avatar , version: :medium %>   
-         <%= f.peviewbox :avatar , version: :medium %>  ## Pass the same version as specified in cropbox

+         <%= f.previewbox :avatar , version: :medium %>  ## Pass the same version as specified in cropbox
+
 6. By default `previewbox` has `100x100` dimensions and `cropbox` defaults to the target geometry for the version.
    `width` and `height` can be specified for these form helpers. BUT If you override ONE of width/height you MUST override both, otherwise passed option would be ignored.
 
          <%= f.cropbox :avatar, width: 550, height: 600 %>
          <%= f.previewbox :avatar, width: 200, height: 200 %>
