browsers will display invalid/corrupt images (best effort)
tried it right now - took a PNG and a JPEG, opened them in a text editor, literally deleted the second half of the file, saved, and dragged them into both Firefox and Chrome - they are displayed instead of erroring out.
there is a classic article why a minimal version of the web with features removed will fail - you removed 80% of the features that YOU think are not important. thats a classic fatal mistake
search the web for different proposals for a minimal web and you will understand - they will have removed some feature they think is bloat but which you kept in your proposal because you consider it critical. which is why you created a new proposal - their minimal proposal is not the right one for you

I think what is lost on many people, ironically even the ones who want to retvrn the web to its former glory, is that the browser tries to display broken, half transmitted content because it happened so frequently due to circumstances completely out of the website operator or the user's control. And in most cases showing a half transmitted web page with half of the closing tags missing is almost certainly better than just outright refusing to show anything.
