Plugin/Solution for clean test on top

I’m currently looking for a plugin or a hack to add a quote and an image on top of the content, and leave the content clean for overviews.

Is there something out there, maybe a extra field for a titel-quote and a titel-image, integrates both on top of the page, but not into the DB-entry of the content itself.

To understand it: here is a posting:
https://www.awakeblogger.com/2008/07/the-5-most-effective-ways-to-raise-your-own-energy-level/

And the Overivew of the post looks like this then:

As you can see, the archive-overview starts with the remark of the image-owner etc. But ist should just start with the first sentence of the real content.

I think other gloggers would benefit from such a solution also, anything out there or any suggestions? Thank you very much.
