Comment 5 for bug 347610

I am not sure I agree with kwurzel.

First - this kind of analysis is doomed to be buggy. You never can guess what users can do with the images. So I am sure there will be cases when this analysis will not work properly.

Second - "images which are higher then wide (or almost squarish), the should be be aligned vertically" doesn't make sense to me. Actually it should work the other way around - you don't make high images to repeat along Y-axes. You rather make them not high at all - about a couple of pixels high since they will be repeated along Y anyway. And of course you want to merge vertically exactly in case you are merging images, that should be repeated along the Y. And thus we have a conflict if you get what I mean.

I would much rather want to see this type of control in the UI for users to be able to select the merging if they know what they are doing or keep "Automatically" (that should be the default option) if they don't really care about how their images are merged or if they are about merging not-repeated images.
