We show that multiphoton interferences of statistically independent light sources can be used to gather information about the spatial distribution of the sources with enhanced resolution. So far, the algorithm has been limited to a regular source arrangement. Here we show that the scheme can be applied also for irregularly distributed sources. After a discussion of the theoretical achievements we present experimental results with up to four independent thermal light sources proving that measurements of spatial correlation functions of higher order can be used as an efficient tool in quantum imaging.
