Yup...any image can be added...i just whipped one up in seconds to iterate that...It can grab the generated image from their site as well, the bbcode would just need an option {}, i figured this was less stuff to manually get for now until this can be worked out to auto parse the embed when someone types in a mit video address.
you can go in the replacement html and find the image located at the xenxero server and point it at any image...if your asking me to make an image for it myself I can do that as well...but I need to eat first. Just let me know.
