hi,
it always a good idea, when your referring to a tutorial to provide a link to the tutorial... that helps a lot in understanding a question....
your first question i don't quite understand, not enough info
now as far as the the last question.....
sounds like what there basically doing...
1. they have there orginal image
2. they make dup layer
3. on the dup layer they'll select all and then use the transform>scale to make the image smaller...
4. once there done with that then there different ways.... select that image on the duplayer, then go to the 1st layers..... then a inverse at this point you can if you want just blur what in side what appears to be a double selection ...
now another popular way to simulate wrap and assummming your looking straight it it....
1. make your canvas larger than the image....
2. then on each side... take your marquee selection tool and make a small selection that includes both a part of the edge of the image and part of the empty canvas..
note: sometimes you don't need to include the empty part of the canvas...
3. then choose transform maybe perspective or distort.... to get the sides you want..
here a couple of tutorial that might helps...
there view of what wrap will look like is different...
