How can i easily view the original embedded image?

edit

When i am embedding a large image via link or uploaded, how can the user easily see the original image?

For example, when using a screenshot inside a question, it may be too small to see the interesting details. Now, i need to right-click and "Open Image in new Tab" to see the original, instead of just clicking on it and "auto-enlarge" it to full size.

Is there a way to activate such kind of functionality?
