Many image files on Wikipedia are vector graphic files.

That is, they are not JPEGs or PNGs.

A JPEG is like a sheet of graph paper where each square is filled in with just one color.

vector graphics, such as files whose names end in .svg trace nice smooth lines.

the computer science educators stack exchange need not host (store copies) of the files directly. Wikipedia already hosts the files, I just want to embed them.

Stack exchange does allow a little bit of HTML, including anchor tags <a>...<\a>. However, it works for grids of colored squares (pixel grids), not vector graphics.

<a href="www.google.com"> <img src="https://en.wikipedia.org/wiki/Cactus_graph#/media/File:Cactus_graph.svg" width="100" height="132">

  • $\begingroup$ I think that you'd probably get a better answer from Meta Stack Exchange since this is a general question about the Stack Exchange sites, but it looks to me like a browser issue. The markdown engine successfully spits out an <img> element, but the image doesn't actually render (at least on my machine). $\endgroup$
