I am editing my thesis, and cannot find any resources on the best way to caption multiple images stacked side-by-side or top-to-bottom for comparison. I quickly put together an example of how I think I should do it.
I think if each image was non-related, then it would be appropriate to caption them as different images, but if they are similar, then I am thinking of using one caption but labelling each image alphabetically.
I am in the UK and the thesis is MSc level, in case that makes a difference.
