Interesting idea. I wonder if it will work with https://stackoverflow.com/questions/5451135/embed-svg-in-svg.

[calidion]

seems not work well.

[chris48s]

I think this is a reasonable feature request. In the meantime, you can probably solve your issue by minifying the SVG e,g:

I ran your image through https://jakearchibald.github.io/svgomg/ to generate that

[platan]

SVG logo from remote inside SVG badge works pretty well, but only served from local filesystem in browser ;-)
I replaced data:image/svg+xml;base64,PHN2Zy... in a content of your badge with https://upload.wikimedia.org/wikipedia/zh/9/99/Tencent_QQ.svg
Hosted here https://gist.github.com/platan/eb6eef2e665abdb490df952916f60eb3 does not work.

[RedSparr0w]

I seem to remember in previous discussions something about not wanting to add support for external images due to the possibility of them being able to track you.

_Note: from memory, so i may be mistaken._

Also as seen above in @platan's comment, it does not seem to work when used in an <img src="">, although it may work in an <object>?

related Issue: #760

[chris48s]

Thanks for posting that. I'm going to close this as a dupe of https://github.com/badges/shields/issues/760

Reading that I think I'm convinced that adding this feature would introduce unnecessary vectors for abuse/attack that would be hard to mitigate. OP's original issue can be solved by minifying.
