Please remember that the non-free content criteria require that non-free images on Wikipedia must not "[be] used in a manner that is likely to replace the original market role of the original copyrighted media." Use of historic images from press agencies must only be of a transformative nature, when the image itself is the subject of commentary rather than the event it depicts (which is the original market role, and is not allowed per policy).
