So you can post without adding to the license, but it must be an original design that you have digitized OR artwork that you have purchased with permission to digitize it. You must also give credit to the artist. ;)
You do not need a license. You do need to make sure the design is your original design, digitized by you. If you used someone's artwork to create your design you need to give credit to that person in the proper section and be sure it was OK to use that art.
