Using thumbnails with Wijering player
If you are using flash node with the Wijering media player and SWF Tools then it is very easy to set a thumbnail that will display before the movie plays. To do this we need to provide the player with the path to the thumbnail image via a flash variable.
To do this with flash node simply add image=/path/to/image/file to Flashvars, found under Advanced flash node options when creating/editing a node.
If you upload the thumbnail using the upload module then you can simply write image=image filename. In this case just attach the image file when you create the node and flash node, SWF Tools and Wijering player sort it all out between them. Don't forget to uncheck the "List" option of the uploaded image file, unless you want people to be able to download the thumbnail!
If you upload the file by some other means (e.g. FTP) so that it isn't in your Drupal files directory then you'll need to put the full path to the image, rather than just the filename.
Note - the Wijering player supports many other flash variable parameters. You can pass these via the Flashvars field as well. For a list of parameters refer to the Wijering player supported flashvars documentation at jeroenwijering.com.

Flashvars not showing
Flashvars are not showing even when I enter them in the node edit screen. I know this because when I view source of published node, the inputted flashvars are missing. Please advise!
Also, does anyone know if the JW 4.0 player settings in SWF Tools allow for Control bar type options? (i.e. overlap or default/bottom)?
I'm seeing the same thing
Never mind - I found the problem is documented here -> http://drupal.org/node/293473
I'm seeing the same thing with respect to the flashvars
Control bar setting for the JW Media Player 4
The control bar type can be set on the JW Media Player 4 configuration page, or you can over-ride it on a case-by-case basis by using the flashvar
controlbar=over|bottom|none________
