Is there a generic way to embed all types of media, including images, in
html? The current way cchost trys to deal with thumbnails is by cramming
whatever file has been uploaded, into the <img src="" />

Cool...Inkscape sets the viewBox to the canvas size now. So, I think for
our purposes, all we would need to do on our side is open and save our
current collection to fix this.
