SVG files are currently not supported as logos, nor can SVG information be stored on any part of the website in a usable form. If I upload an SVG, it gets converted to a JFIF image, but the file extension is not changed, so it is not useful. Also, why do that when you can just keep it SVG?
It would be nice to use SVGs as logos or other images, since they scale better than raster images.
