The potential of hard X-ray imaging to tackle scientific questions can be substantially increased when the dimension time is accessible. Ultra high-speed X-ray imaging related to materials sciences is of special interest. Nowadays, unprecedented temporal resolution with hard X-ray imaging can be reached at synchrotron light sources thanks to indirect detection schemes combined with high-speed cameras. Storage rings like European Synchrotron Radiation Facility can be operated in so-called timing-modes with reduced bunch number but increased electron bunch charge density per singlet. The polychromatic photon flux density at insertion-device beamlines during timing-modes is sufficient to capture hard X-ray images exploiting the light from one singlet. Hence, X-ray imaging depicting processes on the picosecond scale is nowadays accessible. Additionally, direct transmission with diffraction imaging can be combined to track crack propagation in crystals. Future developments and their potential in the frame of the proposed upgrade of storage rings will be discussed.
