First, the plugin is great. Works as described. Kudos to the developer.
I'm currently adding a PNG image of youtube play button (red play button we see before playing a YT video) on every thumbnail manually. This is very tedious.
I was wondering if I can do the following:
1. Upload the youtube image (PNG) to WordPress. (I can do that)
2. Edit this plugin and use PHP magic to superimpose the Youtube play button right in the middle of the thumbnail. (something like this : http://halgatewood.com/youtube/) and then generate a thumbnail that has the play button on it.
Can someone please guide how to achieve this. In which files do we need to make changes?
