Caption: Figure 4.

HST ACS or WFPC2 images of a selection of clusters with ages less than 2 Gyr, except for VDB0 whose image is from the LGS V band. The HST images were taken in either F555W or F606W. The spectroscopically determined ages in Gyr are listed for each image, as is the camera used ("A" = ACS, "W" = WFPC2), to aid in comparison since in general the ACS images are deeper. A comparison of old M31 globular cluster is shown, as are two candidates that turned out to be asterisms. The scale is the same for all images; except for the two small ones, each image is 10'' on a side. The images are ordered by descending mass, starting at the top left.
