Try sending both datasets to the same Inspector and check if they overlap.

Add a reprojector to each one and set to read from feature and then define a projection. Then output to a visualizer to view them in the same projected space.

I agree, as long as both datasets are already georeferenced. If a raster such as a PNG file does not have a world file, it may be necessary to georeference it first using e.g. the RasterGeoreferencer.
