Not tested:

Supose you have image_left and image_right
Create a new image same height, double width.
add two layers to it, set color to transparency.
copy/paste left image to the left of one layer.
copy/paste right image to the right of the other layer, overlaping a
small portion.
add layer mask to both layers
fill the layer mask of each layer with:
white where it has the image, black where there is the image in the
other layer, gradient from white to black where two images overlaps.

Hope this helps
