erect  means upright.virtual images are always erect.
real img: when light rays actually meet at some point after reflection or refraction, then the image formed is called real img.
it can be projected on any thing.
it is always inverted.
virtual: when the light rays do not actually meet but appear to come from the point after reflaction or refraction then the image is virtual image.
it is always erect.
