It is recommended to make the dying person face the qibla such that the soles of his feet are facing the qibla, so if he were to sit he would be facing it with his face. It is obligatory to make him do so after his death. It is recommended after ghusl for the body to be placed perpendicular to the direction of the qibla.
One can remove the barrier and then wash the area to complete the ghusl, as long as nothing had occurred thus far that would invalidate the tahara, such as the passing of wind or sleeping.If such a thing has occurred, then the area should be washed as mentioned above and then wudhu should be performed before offering the prayers.
It is permissible to look at the picture without sexual desire. But if looking at her is shameful for her, as she observes the hijab, or is respected in the society, and similar reasons, it is prohibited to look at the photograph even without lust.
