Try something like this
[rows, columns, numberOfSlices] = size(image3d);
for slice = 1 : numberOfSlices
    thisSlice = image3d(:,:, slice);
    baseFileName = sprintf('Slice %d.png', slice);
    fullFileName = fullfile(folder, baseFileName);
    imwrite(thisSlice, fullFileName);
end
To get them back, use imread(). To tack onto a 3D image, use cat(3, image3d, thisSlice).
