Don't think so. Wikipedia is blocking new users with less than 10 edits, don't know how they do it, but kinda doubt it can be done here, as it will need new group for new users or something. Otherwise there should be a way to change/add a message to the upload image bubble. "add a photo" -> "Upload a Photo to the Wiki" bubble, likely that should be able to be customized somehow.
