Doesn't work like that. First: While it might be possible to add that helper to the relevant controllers, there's no need to do so: Radiant tags are used in layouts and snippets instead of ERB syntax. In fact, helper methods aren't even accessible directly from radius tags, because a "context" in which radius tags are being evaluated isn't the same as an instance of a controller class.
So the way to go would be a radius tag used to encode its contents to b64. See the developer docs for details: http://wiki.github.com/radiant/radiant/adding-custom-radius-tags Could be something like this: <r:base64:encode> ... stuff to encode </r:base64:encode> or <r:base64:encode asset="path/to/image/or/whatever" /> HTH.
