This log was inspired by "How to Read Wittgenstein" and "Ludwig Wittgenstein: the duty of genius" by Ray Monk. It is based on reading Tractatus Logico-Philosophicus by Ludwig Wittgenstein translated by D. F. Pears & B. F. McGuinness (Routledge and Kegan Paul:1963)

An image depicts its sense.

What the image and what it depicts have in common is the logical form of representation. An image depicts reality by presenting a possible way that matters of fact may be the case or not. It presents a possible situation in the realm of logic and implies that the situation it presents is possible. It corresponds to reality or not; it is correct or incorrect; true or false. The image portrays what it portrays, independently of its truth or falsehood, by means of its representational form.

What an image depicts is its sense. Whether or not its sense is congruent with reality constitutes true or false. So in order to tell whether an image is true or false, we must compare it to reality. It is not possible to determine from the image alone whether it is true or false; there is no a priori true image.
