Method: Inkcite::View#image_url

Defined in:
lib/inkcite/view.rb

#image_url(src) ⇒ Object

Returns the fully-qualified URL to the designated image (e.g. logo.gif) appropriate for the current rendering environment. In development mode, local will have either images/ or images-optim/ prepended on them depending on the status of image optimization.

For non-development builds, fully-qualified URLs may be returned depending on the state of the config.yml and how image-host attributes have been configured.

If a fully-qualified URL is provided, the URL will be returned with the possible addition of the cache-breaker tag.
