Instance Method Details

#image_tag(source, options = {}) ⇒ Object

In HTML <link> and <img> tags have no end tag. In XHTML, on the contrary, these tags must be properly closed.

We can choose the appropriate behaviour with closed option:

image_tag "/images/foo.png", :alt => "Foo itself", :closed => true

The default value of closed option is false.
