Widget showing next to specific paragraph – plugin?

Image of the problem: Screenshot

Is there a plugin that makes a widget appear specifically next to a block of text (identified by a shortcode)?

Pretty much like in the picture just above. I don’t have enough space on the content block, and adding a picture next to it isn’t aesthetically pleasing. Therefore, I’d like to use the widget area to put the image, right next to specific parts of the text.
Thank you!
