How to change default-image-extension for one specific figure?

[gdietl]

I'm working on a quarto book which I'd like to render as HTML and PDF. The automatically generated figures are either SVG or PDF files, depending on the output format. This is working fine.

However, there is a problem when including other images via the command

As far as I understood, I need to work with "default-image-extension" in order to tell quarto to use different image formats for the different output formats as follows:

format:
  html:
    fig-format: svg
    default-image-extension: svg
  pdf:
    fig-format: pdf
    default-image-extension: pdf

Now, I would like to insert an animated gif where I have prepared a screenshot in PDF format for the PDF output format. So, when calling

![](image)

quarto should choose image.gif when producing the HTML output and image.pdf when generating the PDF output.

Is there a way of changing the default-image-extension for only one specific figure?

Conditional content and hardcoded its extension 🤔
See https://quarto.org/docs/authoring/conditional.html.
