Make a picture (.jpg) with name as a video and put it in a folder with the video.
Eg:
http://site.com/video/itfork.vlf
http://site.com/video/itfork.jpg
You can put your logo on the picture your site.
For example a site
neformals.by/video/prikols/plus100500.html
To do this, change the code in sources.php (sitelocation/plugins/content/jw_allvideos/includes)
Before
<param name=\"flashvars\" value=\"file={SITEURL}/{FOLDER}/{SOURCE}.flv&[b]image={SITEURL}/{FOLDER}/{SOURCE}.jpg[/b]&autostart={AUTOPLAY}{CONTROLBAR}&fullscreen=true\" />
After
<param name=\"flashvars\" value=\"file={SITEURL}/{FOLDER}/{SOURCE}.flv&[b]image={SITEURL}/images/stories/backfonpl.jpg[/b]&autostart={AUTOPLAY}{CONTROLBAR}&fullscreen=true\" />
