This I found from a Goggle and I quote it to point to the area I think is open for other interpretation.

ABSTRACT
We present new weak lensing observations of 1E0657..558 (z =0:296), a unique cluster merger, that enable a direct detection of dark matter, independent of assumptions regarding the nature of the gravitational force law. Due to the collision of two clusters, the dissipationless stellar component and the uid-like X-ray emitting plasma are spatially segregated. By using both wide-eld ground based
images and HST/ACS images of the cluster cores, we create gravitational lensing maps which show that the gravitational potential does not trace the plasma distribution, the dominant baryonic mass component, but rather approximately traces the distribution of galaxies. An 8. signicance spatial oset of the center of the total mass from the center of the baryonic mass peaks cannot be explained with an alteration of the gravitational force law, and thus proves that the majority of the matter in the system is unseen.

The bold I added to draw attention.
My contention is that no photos can be taken of dark matter and this illustrates my belief that any "photos" are indeed showing where they believe dark matter to exist.. an existance I say is from an inference that the current understanding of gravity requires a mass interaction. I suggest different is possible if one can except that gravity does not attract but comes from the force of dark energy..which is a pushing force.
Clearly if one sees gravity as a force of attraction one will need matter to cause the attraction, if one sees the Universe in the context of dark energy and the force of gravity effectively as a pushing force I believe that the necessity to find dark matter will disappear. The areas which they conclude hold dark matter I suspect hold no such thing but are in effect areas where the force of dark energy (gravity rain, universal pressure or whatever to describe the side I am on) is reduced due to a shielding from outside that area.
I hope you can understand what I am attempting to convey..simply so you can assess it fairly and then dismiss or more unlikly accept my proposition.
