Abstract: Discussion of images of young circumstellar disks both in visual/ near-infrared scattered light and thermal infrared emitted light, showing the state of the art in such imaging. Scattered light imaging with HST provides temperature independent information on disks at high angular resolution as well as the potential for the detection of high mass planets orbiting within them. Midinfrared imaging is still the most sensitive way to detect disks, but can reveal structure only very close to stars where dust temperatures are high. Together, the two types of images give information on the disk grain albedo that can help constrain grain composition. Results highlighted regarding three disks around A-type stars (in order of increasing age): HD 141569, HR 4796A, and beta Pictoris.
