From the New/Edit command you can access the following configuration options for your maze.

Title
This should be a short description of what the maze is. For example, if the maze is based on an image of an apple, you might want to title it simply, "Apple."

Keywords
Keywords are helpful only if you intend to share your maze publicly on the site.  Keywords will help visitors find your maze.  Enter words and phrases separated by commas. For example, if the maze is an apple, you could enter "apple, fruit, food, healthy food" and so on.

Keywords are optional, and if you share your maze, the site administrator will probably tweak your keyword list for you, so don't stress over it too much!

Blank Canvas
Check the "blank canvas" checkbox if you don't have an image file you are basing your maze on.  If you choose this option, you will be required to create an image on a "paint" style canvas.

Add New Media Files
If you are not using a blank canvas, you must upload an image file (jpg, png, or gif) to be used as the basis for your image. When you choose an image to use, look for one which has high contrast. Dark portions of your image will become the interior of the maze shape, while light regions will be the outside.  If the image has a lot of mid-tone regions, you may need to do a lot of manual editing on the maze canvas before generating your maze.
