Strictly speaking it was not an X-ray image, it was an X-ray diffraction pattern cause by the scattering of X-rays from the DNA structure. There's a fair bit of interpretation required to go from from a diffraction pattern to a structure but nevertheless a very important step in the discovery sequence.
