@Tyler_S I think now the process to declare the license for your wallpaper image is to upload your artwork (wallpaper) to WikiMedida Commons from the WikiMedia’s Upload Wizard first after creating your account on WikiMedia. In the process of the uploading the image, you are asked the lincense. Then Caleb is going to upload his wallpaper later considering your license.
Could you do that? Thanks!
Sorry just moment. Sorry for confusing you.
