A GUID is a unique identifier for each element in your Media RSS feed. If you include GUIDs in the following way, PicLens will not preload the Media RSS feed you expose.
GUIDs can be anything composed of any length of hexadecimal digits, and need to be unique for each <item>. PicLens supports the ability to specify unique GUID identifiers in your Media RSS Feed:
<item>
<guid>00001111</guid>
<link>imgs/image.jpg<link
<media:content> url="imgs/image.jpg" />
<media:thumbnail> url="imgs/image_thumb.jpg" />
...
</item>
Your declared GUIDs must match up with the corresponding elements in the HTML with <span class="mbf-item">#gallery guid</span> tags:
<img src="imgs/image_thumb.jpg" />
<span class="mbf-item">#gallery 00001111</span>
The <title> tag displays the title (weird, huh?) of the item, and the <media:description> tag specifies the description, like so:
<item>
<title>Image Title</title>
<media:description>Description of my Image</media:description>
<media:content url="http://www.mywebsite.com/image.jpg" />
<media:thumbnail url="http://www.mywebsite.com/image_thumb.jpg" />
</item>
If you're running an IIS server, you need to enable RSS Mimetypes (which are not enabled by default). If you've got an Apache server, you'll need to disable deep linking protection to allow PicLens to display full size images.
The <link> tag of each item in your Media RSS feed determines where the globe redirects the user. For example, if you want your user to redirect to www.PicLens.com, use:
<item>
<link>www.PicLens.com></link>
<media:content url="http://mywebsite.com/a.jpg" />
<media:thumbnail url="http://mywebsite.com/a_thumb.jpg" />
...
</item>
