The Wide-Field Camera 3 (WFC3) on HST has two channels, one in the UV-optical range and one in the near-IR, that are producing excellent imaging results. Here we review some of the features that observers can encounter in their data, some due to detector and instrumental artifacts and others due to the space-based environment of HST. This includes the nature of the near-IR background seen by HST/WFC3, scattered Earth light, optical ghosts, and isolated regions of reduced sensitivity in the IR field of view ("blobs"). We review processes by which some of these can either be avoided to begin with or mitigated in the data reduction and analysis process. This includes the appropriate use of the data quality flags that are included in the calibrated WFC3 imaging products.
