* @param Title $title Title object of the file (not the currently viewed page)
* @param File $file File object, or false if it doesn't exist
* @param array $frameParams Associative array of parameters external to the media handler.
* Boolean parameters are indicated by presence or absence, the value is arbitrary and
* will often be false.
* thumbnail If present, downscale and frame
* manualthumb Image name to use as a thumbnail, instead of automatic scaling
* framed Shows image in original size in a frame
* frameless Downscale but don't frame
* upright If present, tweak default sizes for portrait orientation
* upright_factor Fudge factor for "upright" tweak (default 0.75)
* border If present, show a border around the image
* align Horizontal alignment (left, right, center, none)
* valign Vertical alignment (baseline, sub, super, top, text-top, middle,
* bottom, text-bottom)
* alt Alternate text for image (i.e. alt attribute). Plain text.
* class HTML for image classes. Plain text.
* caption HTML for image caption.
* link-url URL to link to
* link-title Title object to link to
* link-target Value for the target attribute, only with link-url
* no-link Boolean, suppress description link
*
* @param array $handlerParams Associative array of media handler parameters, to be passed
* to transform(). Typical keys are "width" and "page".
* @param string|bool $time Timestamp of the file, set as false for current
* @param string $query Query params for desc url
* @param int|null $widthOption Used by the parser to remember the user preference thumbnailsize
* @since 1.20
* @return string HTML for an image, with links, wrappers, etc.
