For those of you that don't want thumbnails, you can completely ignore this video. But since a couple of people have asked me lately, here are some things you should include in a request:
1. What video or series the thumbnail is for.
2. A general idea of what you want on it (i.e. Minecraft forest with words "Noob Mines Craft")
3. A way to give it to you (a spam email is recommended)
Though I will often have it done within 24 hours, it completely depends on my schedule.
And while chances are we'll never be in a court case over a thumbnail, the thumbnail does not belong to you and I can use it however I want.
