Hi Toph Katara200. Well, as I see that you are new here, first off, welcome to this wiki. =) We hope you enjoy being on here. ^^
Unfortunately, the file you recently uploaded - New.jpg - had to be deleted because, per official policy, images cannot be uploaded just for message walls or user profiles. They have to be used on actual wiki articles. You are welcome, however, to post an image that is already used on the wiki or link the image you uploaded from another site, like Photobucket. =) Oh, and you don't have to post your greeting in a message on your wall; you can edit your message wall itself and the greeting will automatically be at the top for all to read.
If you have any questions, feel free to ask me. ^^
