I have thumbnails enabled and I've implemented the small changes to make a larger version of the thumbnail appear on the single.php page. It works great.
The problem I have is that I want to use the thumbnails always on the index.php, but on occasion, not have it appear on the single.php. Sometimes instead of showing the thumbnail on the signle post, I just want to show an embedded video.
How can I disable the thumbnail from appearing on the single.php of *some* pages, but still have them appear on the index.php?
