I was thinking a widget might be needed just for display. The svg code
arrives complete with tags so really all it needs is a mechanism to
persuade the admin it is safe to render as is.
I haven't seen such a (probably insecure) "feature" previously. I've
looked throug
es in the Admin. At this
stage all it displays is the svg source.
What is the correct way to make the image appear in the Admin?
Do I need a special field inheriting from TextField? Do I need a special
widget? Is there a way to mark admin field values as safe?
