setup 3 or 4 polygon or nurbs planes and position them like the image shown above.

Then texture them with each image. If you know how to texture skip this bit, if not read on.

1) Then right click on one, assign new material > lambert.

2) Go into your attribute editor (ctrl + a) go across to the right to the Lambert tab.

3) Go down to color click in the box on the right

4) where it say image name click on the right box again and locate your image for that particular plane.

IMPORTANT:Obviously nothing with match up, so heres the clever bit. In photoshop you need to measure how big the image is either in cm, mm or whatever. for example 450 mm x 300mm. This is important as you need to be precise in Maya or it will look out of proportion.

Now in Maya go to Window > settings/preferences > prefferences

scroll down to settings and change Linear to whatever you used in photoshop i.e cm or mm or foot etc.

Now you can shape your polygon planes to the exact size

sorry i shouldve said the 'important' bit at the beginning
