The agreement or disagreement or its sense with reality constitutes its truth or falsity.
A picture agrees with reality or fails to agree; it is correct or incorrect, true or false.
There must be something identical in the representation and in what it represents, to allow the one to be a representation of the other.
A picture can depict any reality whose form it has. A spatial picture can depict anything spatial, a coloured one anything coloured, etc.
These correlations are, as it were, the feelers of the picture's elements, with which the picture touches reality.
So a picture, conceived in this way, also includes the pictorial relationship, which makes it into a picture.
