QOOHL

This image is related to another image I really feel near to me. That image is related itself to another image in charge of an iconic role, so does mine.

The sharpest and simplest way to define this kind of relation is a vector sharing the same direction but an opposite verse (and less magnitude).

To define it in a a more complex, analytic and time consuming way it could be possible to place the two related images and the related iconic images in a structural semiotic square and spend a nice hours on it.

Otherwise, to avoid excessive cognitive load, this relations can also be expressed at least in terms of logical not, symmetry, opposition, reversal, negation, contradiction, reaction, inversion, contrast, counterpoint, mirroring, flip etc...
