/**
* Configure a field to accept one image file and automatic resize
*
* In the parameters you should pass one hash containing the name of resize (the key of hash)
* and the resize configuration (the value)
*
* Resize configuration:
* Its just a simple string following "WIDTHxHEIGHTxMODE", where:
* - WIDTH: the width of resized image
* - HEIGHT: the height of resized image
* - MODE: the resize mode, see Ra_Image library for a full description about
* resize modes
* You can pass zero (0) for width OR height, this way the library will calculate the proportional
* size.
* You can use null to get a original version of image
*
* Example:
* $this->field_as_image("my_image_field", array("default" => "300x0x0", "thumbnail" => "30x30x1", "original" => null));
