Central implies image-potentially characteristic

From Groupprops

This article gives the statement and possibly, proof, of an implication relation between two subgroup properties. That is, it states that every subgroup satisfying the first subgroup property (i.e., central subgroup) must also satisfy the second subgroup property (i.e., image-potentially characteristic subgroup)

Statement

Suppose H is a central subgroup of a group G: H is contained in the center of G. Then, H is an image-potentially characteristic subgroup of G: there exists a surjective homomorphism ρ:KG and a characteristic subgroup L of K such that ρ(L)=H.
