This plugin allows to show the live video of a webcam or a netcam. 
The image is refreshed with the specified time. 
If the refresh time is too low the image could skip. 
To get good results it is better to set a refresh time between 1000 and 5000 milliseconds.
A widget is also available.
Shortcode parameters
<ul>
<li>url (required): webcam URL to a single image of the live stream</li>
<li>refresh: image reload time in milliseconds (default: 1000)</li>
<li>width: image width (ex. 100%, 640)</li>
<li>height: image height (ex. 50%, 480)</li>
<li>click: enable/disable click event to freeze the current image</li>
</ul>

Sometimes we need to show the different images of a video on our post instead embedding the whole video. To give a video snippet it is a quick way to embed web video thumbnails on your post (youtube and vimeo only this time). More video sites support will be added soon.
How does this plugin work ?
You need to put some keywords with your video URL as below:
images_link : Fetches image thumbnails 
images_withlink_link : Fetches image thumbnails with a hyperlink to original video
e.g. images_http://youtube.com/watch?v=xxxxxx
e.g. images_http://vimeo.com/xxxxxx
