Which kid in America has the most creative Halloween costume in the pumpkin patch? That's what we intend to find out with your photos and the help of celebrity judge Heidi Klum, who will select the Grand Prize winner.

The Grand Prize? Patch will whisk the winner to New York or Los Angeles for a two-day, three-night trip for two that includes a meet and greet with Heidi, plus a donation of $1,031 to a local charity of the winner's choice. Nine runners up will also get a $1,031 donation from Patch to a local charity of their choice.

Entering is easy. Just upload a photo of your kid into this page, 12 years of age or younger, in his or her Halloween costume. Entries must be made by the parent or legal guardian of the child photographed. Full rules are here.

Submissions must be received before 9pm (local time) on Halloween night (October 31st).

Good luck and be sure to support Heidi Klum’s efforts to feed the hungry. Visit Trick or Treat for UNICEF! And find more of Heidi’s Halloween favorites at heidiklum.aol.com.

How to upload your picture:

To upload a picture, you need to be a Patch user, so if you don’t yet have an account (it’s FREE), you will be asked to sign up when you attempt an upload.

1.     To add a photo, click on the link under this article that reads “Submit your photos & videos.”

2.     A new window will open; click "Choose files to upload." This will take you to your computer files, where you can choose the image you wish to add.

3.     One you have chosen a photo to be uploaded, click OK or OPEN (depending on your system) and you will then see a screen with a link that says "Start uploading." Click that.

4.     Your photo will upload, and when it is done the computer will ask you what you want to do next. Click "Edit your new photos." This is where you add your caption information for the contest: the child’s name, entrant’s name, and the local charity of choice.

Good Luck and Happy Halloween!
