2. In 3rdparty/plugins/S5/ui/default/slides.js, go to line 384 and replace the following code block:

	controlsDiv.innerHTML = '<form action="#" id="controlForm"' + hideDiv + '>' +
	'<div id="navLinks">' +
	'<a accesskey="t" id="toggle" href="javascript:toggle();">&#216;<\/a>' +
	'<a accesskey="z" id="prev" href="javascript:go(-1);">&laquo;<\/a>' +
	'<a accesskey="x" id="next" href="javascript:go(1);">&raquo;<\/a>' +

with the following code block:

	var newURL = location.href.replace(/\/slideshow$/, '/edit');
	controlsDiv.innerHTML = '<form action="#" id="controlForm"' + hideDiv + '>' +
	'<div id="navLinks">' +
	'<a accesskey="t" title="toggle views" id="toggle" href="javascript:toggle();">&#216;<\/a>' +
	'<a accesskey="z" title="previous" id="prev" href="javascript:go(-1);">&laquo;<\/a>' +
	'<a accesskey="x" title="next" id="next" href="javascript:go(1);">&raquo;<\/a>' +
	'<a accesskey="e" title="edit" id="edit" href="'+ newURL +'">&#177<\/a>' +

3. In libs/Wakka.class.php, go to line 1037 [versions 1.1.6.2 & 1.1.6.3 only] or to line 1743 [version 1.1.6.4 only] and replace the following code block:

        // grabcode page handler
        elseif ($this->method == "grabcode")
        {
            print($this->Method($this->method));
        }
        elseif (preg_match('/\.(gif|jpg|png)$/', $this->method))

with the following code block:

        // grabcode page handler
        elseif ($this->method == "grabcode")
        {
            print($this->Method($this->method));
        }
        // slideshow page handler
        elseif ($this->method == "slideshow")
        {
            print($this->Method($this->method));
        }
        elseif (preg_match('/\.(gif|jpg|png)$/', $this->method))
