Vocaloid Wiki:Image guidelines and w:Community_Central:Central_user_pages

""In addition, do not use the Wikia as an imagehost. Personal pictures unrelated to Vocaloid or will be of no use, must be hosted to an imagehosting site such as Photobucket, Tinypic, or Imageshack.""

It is not asking much. TinyPic (for example) is free to use without creating an account, so is Imageshack. Wikia staff in general prefer their services be used for growth of the wiki subject and not thousands of people using it as an image host to decorate a users page.
