I have just successfully installed the revised Video Module, which allows for six custom fields to be added to an uploaded video.
I would now like to theme the new video node and make one of the custom fields an image field so that one sees a static thumbnail jpeg before watching the video clip.
The module wraps the six custom textfields in a div with a class of "videofields" and each separate line is given a class of either "odd" or "even".
I'm a little confused about how to proceed: do I want to enter the path to the image in one of the text fields (and therefore write it into the database table) and then figure out a way to alter the underlying html elments to make what was formerly a line of text now a jpeg? (I presume this would be done by playing around with the module's PHP code and writing out something like img src="path to image.."
Or do I want to go down the path of creating a page called node-video.tpl.php as outlined here? Do I need to incorporate the image module somehow? It would be nice to have a way to upload still images through a browser, but I'd be happy enough just to be able to upload manually and hardwire in the pathnames.
I'm conceptually stuck, but in seeing that the contributor to the video module has done just this on his site I'm hoping there is a relatively straightforward way to do this.
