I think this is the best ROSAT image they have: http://cade.irap.omp.eu/documents/Ancillary/4Aladin/RASS/
For XMM Newton it's this one: http://skies.esac.esa.int/XMM-Newton/EPIC-RGB/
Yes, the X-ray images don't look so nice. But they are the most relevant for gamma-ray astronomy, because hard X-ray emission is nonthermal emission, i.e. also shows the cosmic particle accelerators.
There is no great X-ray survey yet. We could mention that e.g. http://www.mpe.mpg.de/eROSITA will be available in the coming years and then also some day on gamma-sky.net.
If you want to mention more future data and surveys, you could also mention that CTA is coming and will do nice surveys of the TeV sky: http://adsabs.harvard.edu/abs/2013APh....43..317D
But I did not mention that http://www.mpe.mpg.de/eROSITA (yet).
Closing this issue...
I've sorted the images in Table 1 according to waveband, it now looks like this: https://github.com/gammapy/gammaskynet-gamma2016/blob/master/proceeding/tables/image_table.tex
The MWL data that's most relevant to compare with gamma-ray data is other non-thermal emission. That means mostly radio and X-ray.
Currently there's no X-ray image. Suggest you add one for ROSAT and XMM here (we can add it to the webpage later).
