An HTML user agent may activate hyperlinks indicated by <IMG> and <INPUT> elements concurrently with processing the document; that is, image hyperlinks may be processed without explicit request by the user. Image resources should be embedded in the presentation at the point of the tail anchor, that is the <IMG> or <INPUT> element.
<LINK> hyperlinks may also be processed without explicit user request; for example, style sheet resources may be processed before or during the processing of the document.
