In ikiwiki.pm, +the hardcoded list of image file extensions does not include ".svg", which +it probably should unless there's some other issue about rendering SVGs? + +The 'img' plugin also seems to not support SVGs. + +> SVG images can only be included via an `<object>`, `<embed>`, or +> `<iframe>` tag. Or, perhaps as [inline SVG](http://wiki.svg.org/Inline_SVG). +> The [[plugins/htmlscrubber]] strips all three tags since they can easily +> be used maliciously. If doing inline SVG, I'd worry that the svg file +> could be malformed and mess up the html, or even inject javascript. So, +> the only options seem to be only supporting svgs on wikis that do not +> sanitize their html, or assuming that svgs are trusted content and +> embedding them inline. None of which seem particularly palatable. +> +> I suppose the other option would be converting the svg file to a static +> image (png). The img plugin could probably do that fairly simply. +> --[[Joey]] + +>> This seems to have improved since; at least chromium can display svg +>> images from `<img>` tags.
