I would like to create a little game where user would simply move some images around with their mouse to create some shapes.

I found about this possibility in the Nutts Puzzle Demo by Karl Scherer.

However looking into the source code I can`t figure out which part enable to manipulate the shapes with the mouse.

    The very last control statement in the manipulate is 

    {{pts, {{2, 1.5}, ..., {16.1, 16.1}}}, Locator, Appearance -> None},

    This makes an invisible Locator at the center of each polygon.
    It is these that are picked up and moved by the mouse.

    The preceding controls create the 2 popup menus and the 19 rotation sliders.

    Edit: To address the comment, an example using Inset:

    g[1]=ExampleData[{"TestImage","Girl"}];
g[2]=ExampleData[{"TestImage","Girl2"}];
g[3]=ExampleData[{"TestImage","Girl3"}];
Manipulate[Plot[Cos[x^n],{x,0,4Pi},
    Epilog->Table[Inset[g[i],pos[[i]],{0,0},ImageScaled[{.2,.2}]],{i,3}]],
  {{n, 1}, 0, 4},
  {{pos,{{0,0},{Pi,0},{2Pi,0}}},Locator,Appearance->None}]

    Bonus points: Name the “Girl”s in the “TestImage” example data…
