Where is a good site to go to get a picture for an edible image.

I need to find a unicorn for a 6 yr. old birthday

Please, can anyone help me??

When I need something like that, I start with a Google Images search, and usually find something I can use. Good luck.

On google you should use the 'image' finder button and type in unicorn. There are dozens of pages

You may want to try photobucket (dot) com. They have a lot of great images on there that you can use.
