Renders an HTML "img" element. Render the clientId as the value of the "id" attribute.
Handling the Value
If the "name" attribute is present, execute algorithm Common Algorithm for Obtaining A Resource to Render to obtain a Resource instance. Call
Resource.getRequestPath() and output the result as the
value of the "src" attribute on the rendered markup.
Otherwise, if the "url" attribute is present, treat its value as
if it was the value of the "value" attribute. Otherwise, if the
"value" attribute is present, render the value of the component as
the value of the "src" attribute, after passing it to the
getResourceURL() method of the ViewHandler
for this application, and passing the result through the
encodeResourceURL() method of the
ExternalContext.
When handling the "src" attribute,
the value must not be escaped. For example, & must not
be turned into &. If the "styleClass"
attribute is specified, render its value as the value of the "class"
attribute.
This renderer is responsible for rendering its children.
Attributes with a ignored-by-renderer value of
true are not interpreted by the renderer and are conveyed
straight to the rendered markup, without checking for validity. Attributes with a
ignored-by-renderer value of false are interpreted
by the renderer, and may or may not be checked for validity by the renderer.
