You mean merging them by finding the middle value of each pixel? For example if left upper corner pixel on pic 1 is 160,120,70, and the left upper corner pixel on pic 2 is 200,220,30, then the pixel written there will be: 180,170,50. And then with 2 For loops make do that with all pixels. You mean merging that way?
An anoter faster way might be loading each picture as a texture onto surfaces with one face, putting one infront, and one right back, create a camera infront, put their alpha values at 0.50 each, and render. Idunno if that would've worked as you want though.
Sorry if I explained bad :P.
