Choose Thumbnail Used on Homepage

Right now, the system uses a random image from your thumbnail images. I would like to have the option to select the image we use.

I would also like to be able to leave the option for it to randomly choose and sort though different photos each day like it currently does and make the “choose thumbnail” being optional. Marketing wise when people see the same photo eventually their mind blinds it out but the constant chage of photo like there currently is makes events more marketable.
