When you blend the image together, it's best to find images of the same background, that way, it'll look more professional!

firstly, open up PSP9(paint shop pro)!

then open up a new blank piece of  paper, and it has to be transperent!!

then, copy & paste one image onto the blank paper by pressing Ctrl and E!

until u get something like this,  then press Ctrl and D to select nothing.

go to layers >>  New Raster Layer

then copy & paste in the other image by pressin Ctrl and E again!

make sure ur image is overlapping a little bit at the face............

then Ctrl and D again!

then select the eraser tool

turn the opacity of the eraer to "50".

then start erasing till u get wat u like, erase off the part where it's blocking the covered face.

find the crop tool to crop the part that u want and get rid of the extra paper.

and here's my completed blend! good luck!
