free and convenient svg hosting

| I'm just used to the convenient way imgur works, but it happens to
| reject svg files.

I'm curious why that matters. SVG is an extremely
limited tool, graphically. It allows making very big,
very simple images relatively small in terms of bytes.
So it might occasionally be handy for a webpage logo.
(Though there's not much sense saving a few bytes on
the size of a logo image if one is bloating the webpage
with 1.5 MB of javascript slop, which has become
increasingly common.)
If someone downloads your Tux image they're probably
going to prefer a GIF. Even if they have tools to edit SVG
code and know how to use them, why would they want to?
I can see someone editing something like their own webpage
logo, but for just about anything else SVG is a clever idea
with virtually no useful purpose. (It's no accident that
SVG usage is nearly non-existent.)
