Better is to ask github to show you it raw e.g. https://raw.github.com/boostorg/math/master/doc/equations/airy.svg.
Note that github always serves everything as text/plain irrespective. This is apparently for security. Nothing we can do can change that behavior. In other words, you cannot use github as a content server, except as plain text.
... except for github pages, which are designed for exactly this.
Yeah, I always keep forgetting about those. If there ever was a way of not doing project page publishing, that is it. (What they really need is to let you do all that magic subbranch hassle server side, so basically I say I want directory X in the SCM published as HTML and they take care of it). Anyway, my point still stands: without magic subbranch hassle to bounce content through github pages, I know of no way to get github to serve SCM content as anything but text or binary blob. If you have a SVG file in the SCM, github will serve that as text, PNGs are offered for download, not rendered etc. Niall --- Opinions expressed here are my own and do not necessarily represent those of BlackBerry Inc.
