I need images for all of these pictures. Please help if you can. :)

Double the ATK and DEF of a single monster for as long as this card remains on the field.

This card must be sent to the Graveyard after a duration of 5 turns.

"Divine Enlargement Ray"+"Temple"

This card can only attack when player uses the card "Crumble". This card must be sent to the Graveyard after a duration of 5 turns.
