Wish: Allow ImageIntegration to work with only 2 stacked images

[jmurphy]

Occasionally it can be useful to average several stacked images together. In these situations, data rejection is not necessary, so it is possible to use PixelMath to do this. However, an even better result could be obtained from ImageIntegration because this will determine the correct image weights. Just leave the 'Rejection algorithm' at its default setting of 'No rejection'.

My request is to extend ImageIntegration so that it can work in this way for only two images. It currently produces the following error:

I assume it is the rejection algorithms that need at least three images.
If this is the case, could the check be changed so that it is only triggered if there are less than three images and a rejection algorithm has been selected.

Thanks, John Murphy

The normal workaround is to load each image twice, giving 4 images.
