To express how a person or thing comes across, the verbs 'machen' (to make) or 'hinterlassen' (to leave) are often used. When forming an opinion about something, you 'gewinnt' (gain) or 'bekommt' (get) an impression.

'das Bild' and 'der Eindruck' can both describe how you understand a person, thing, or situation in your mind. 'der Eindruck' more often means the feeling or effect that something leaves on someone. 'das Bild' more often means a mental picture that you form in your head. The words are especially close in 'sich ein Bild machen von' (to get a picture of). You can say: you gather information in order to form a picture; after that, you have an impression.
