Computes the path to an image asset in the public images directory. Full paths from the document root will be passed through. Used internally by image_tag to build the image path.

 image_path("edit")                                         # => /public/images/edit
 image_path("edit.png")                                     # => /public/images/edit.png
 image_path("icons/edit.png")                               # => /public/images/icons/edit.png
 image_path("/icons/edit.png")                              # => /icons/edit.png
 image_path("http://www.railsapplication.com/img/edit.png") # => http://www.railsapplication.com/img/edit.png

Public Instance method: image_tag( source, options = {} )

Returns an html image tag for the source. The source must be a file that exists in your public images directory (public/images). You can add html attributes using the options. If no alt text is given, the file name part of the source is used (capitalized and without the extension)

 image_tag("icon.png", :alt => "Edit Entry")  # =>
   <img src="/public/images/icon.png" alt="Edit Entry" />

Public Instance method: javascript_include_tag( *sources )

To include the Prototype and Scriptaculous javascript libraries in your application, pass :defaults as the source.

  javascript_include_tag "xmlhr" # =>

  javascript_include_tag "common.javascript", "elsewhere/cools" # =>
    <script type="text/javascript" src="/public/javascripts/common.javascript"></script>

Public Instance method: link_to(name, address, options = {})

Creates a link tag of the given name using address has the href for the link

The options will accept a hash of html attributes for the link tag. It also accepts 2 modifiers that specialize the link behavior.

• :confirm => ‘question?‘: This will add a JavaScript confirm prompt with the question specified. If the user accepts, the link is processed normally, otherwise no action is taken.
• :popup => true || array of window options: This will force the link to open in a popup window. By passing true, a default browser window will be opened with the URL. You can also specify an array of options that are passed-thru to JavaScripts window.open method.

You can mix and match the options.

  link_to "Documentation", "http://camping.rubyforge.org/", :confirm => "Are you sure?"
  link_to "Help", R( Help ), :popup => true
  link_to image_tag( "thumb.png" ), "/public/images/fullsize.png", :popup => ['My house', 'height=300,width=600']
