all of these can be found doing a simple search for cruise ship images. Just trying to keep it interesting around here. Just do one, maybe two. Here is the list, which I reserve the right to expand at any point 
Muster drill
Picture of a buffet
Ship after a fire
A river cruise ship
Passengers sunbathing
Crowded, and I mean packed, pool area
A water slide
Sail Away
A ship listing
People in port
Port bazaar
Removing a sick / injured passenger
Searching for luggage at debarkation
A ship lit up at night
An iceberg or snow capped mountain
A ships coin
A ships bridge
that should get you started
