Not quite clear if the problem is solved now. If not:
You have to know with what dpi value the png is exported from GIMP. 300 is a good choice. When then importing into LibreCAD set that at the Tool Options bar.

Best insert it at the lower left corner of the frame. Then scale it up 600x (from your 1 inch = 50 feet) with Scale. Up to V 2.1.3 there is a bug that it will seem to be disappeared afterwards, AutoZoom brings it back.
For further advice ask again if needed.
