how to mask an svg shape to an svg image - html

Question

So basically I have a triangular shape and I want to mask it in an image/gif.
<svg width="209" height="143" viewBox="0 0 209 143" fill="none" xmlns="http://www.w3.org/2000/svg">
<path fill-rule="evenodd" clip-rule="evenodd" d="M104.5 0L0.143921 142.5H208.856L104.5 0ZM104.5 10.1551L11.9747 136.5H197.025L104.5 10.1551Z" fill="black"/>
</svg>
<div class="clipSvg2">
<svg viewBox="0 0 300 300" fill="none" xmlns="http://www.w3.org/2000/svg">
<defs>
<mask id="mask11">
<!-- <svg width="209" height="143" viewBox="0 0 209 143" fill="none" xmlns="http://www.w3.org/2000/svg">
<path fill-rule="evenodd" clip-rule="evenodd" d="M104.5 0L0.143921 142.5H208.856L104.5 0ZM104.5 10.1551L11.9747 136.5H197.025L104.5 10.1551Z" fill="black"/>
</svg>
-->
</mask>
</defs>
//Here add some mask=url(#mask11)
<image
width="100%" height="100%" xlink:href="https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQU69UnQwUGs3VTS51AEM2MRTHED0PRl0rMLVw3hdS_95xNdTPqY5_7E3N-pzgp49lrdkY&usqp=CAU"></image>

Answer 1

I'm not sure what it should look like, but here are two examples. The first uses a clip-path. With the clip-rule="evenodd" it is only the "frame" that shows.
The second is a mask. In the mask the path has a white fill – that is what makes the image show.
In both cases I made the viewBox the same aspect ratio as the image to make the image take up the entire space of the SVG.
<svg width="300" viewBox="0 0 284 178" xmlns="http://www.w3.org/2000/svg">
