Manipulating images

These are some pictures from our trip to The Netherlands. The first picture is from the Efteling park and the second picture is from the youth hostel where we were living. The manipulated picture shows the teachers from Greece and Spain who instead of entering the  Efteling park they seem entering  the youth hostel where we were living in this time ! This realistic picture was designed using a programm called Gimp and it 's working almost the same way  Photoshop does !
