They seem like good sources to help keep track of new developments in dark matter and other cosmological questions. Thanks to Jon Hanford for the lens links.

Similar to the Strong Lenses COSMOS Page, current images & info on lensed quasars can be found here and the site is updated periodically with links to new images, info & newly discovered systems of this type. Both sites are highly recommended for those interested in gravitationally lensed systems and current research being performed on them.

It includes HST images & Keck spectra to help determine the physical characteristics of both the lensing galaxy (at a redshift of 0.73) & the magnified image of the LBG. Lensed systems such as this one can give astronomers valuable information on distant, forming galactic systems that would otherwise prove too faint to accurately examine due to their great distance. Websites such as the Strong Lenses COSMOS Page at http://cosmosstronglensing.uni-hd.de/ provide current images & info on these rare and unusual gravitational lenses and are frequently updated with current info & newly discovered objects. These systems not only provide good sources of information on chemical abundances, star formation rates and other physical characteristics of the lensed galaxies, but can also provide info on Dark Matter distribution in the lensing galaxies themselves. These systems are sure to be examined in detail across the entire electromagnetic spectrum in the coming years.
