There is, but it seems to be more in-depth than I have time to get into right now. For starters, check out the Custom Thumbnails plug-in and the author’s discussion on how he built the system to generate custom thumbnails.
If you want your own solution, you’ll need to hook in to the ‘image_downsize’ filter, though I’m not 100% sure what you’d use with it … but I can research it later and get back to you.
It looks like you can tell WordPress to replace any thumbnail with one you specify, but whether you want this applied to all thumbnails or just specific ones is something you’ll have to explain.
So basically, what’s your ultimate goal here?

Thanks.
My ultimate goal is for all posts without any image in the post to use a thumbnail that is in my media library.
I have plenty of posts with no specific thumbnails and I want to use a standard default image for ALL those posts so it is a huge time saver not to have to manually add the default image.
