Lensed images of HS 0810+1154 (left) and SDSS J1353+1138 (right). Left: HST ACS F555W image of HS 0810+2554 showing the four magnified images of the background quasar in fold lens configuration: the C and D images are spatially resolved, while the pair A+B is blended together. At the centre, we can see the emission from the foreground lens galaxy. Right: V and H-band images of SDSS J1353+1138 taken at the UH88 telescope (upper panels) and corresponding images after the subtraction of A and B components (lower panels), clearly showing the lens galaxy (component G). Image from Inada et al. (2006).
