How to have the thumbnail be different from the post

First get two images, preferably have the thumbnail smaller than the picture(s) you are going to actually have in the post.

Then hit "Share to Gallery"

Note: If the thumbnail doesn't upload first, it might be too big.

Once here, fill in the information needed for the post and before hitting "Share" get rid of the thumbnail (Hit the grey "X" all the way right of the picture).

Done

Now because you guy got me to the frontpage, let this also be an upvote party. So an upvote party is when you comment and I upvote it. Easy as that. I'm doing this to give back to Imgur for getting me to the frontpage. Here's the post: http://imgur.com/gallery/WWrf8 Now if want to have an upvote party, do it.
There are only four rules,
1) Only when you make it to the frontpage is when you can post one.
2) You must upvote every single one of the comments, even the ones you hate.
3) If there are any Upvote Party posts that make it to the frontpage, you can't make an upvote party post off that.
4) An Upvote Party ends when you have another Upvote Party or when you say it should (at least a day) Thank you and enjoy the day.
