Is your feature request related to a problem?

I want to document an api which returns tiles for a map. The responses are all images for which i have examples, but swagger cannot display them in a pretty way. Currently it just base64-dumps the data.

Describe the solution you'd like

It would be nice if images like png and jpg could be displayed as viewable examples. directly in the examples section.

Describe alternatives you've considered

An alternative solution which would also work would be to provide a link in the examples section, rather than displaying the image/binary data.

Additional context

An example of how it's working/looking currently:

(i use externalValue with a url and the correct headers exist when calling the url)

Start by reproducing the issue in Swagger UI with the supplied OpenAPI response containing an image/png example and externalValue URL. Trace the examples display path and compare the current base64 output with the requested inline image or link behavior; the work is done when PNG and JPG examples are viewable directly in the examples section.
