ImageWidget buffer does not render nicely in static notebook view about astrowidgets HOT 8 CLOSED

Hi! I am Micky, looking for apply for GSOC for this project!
I was looking into this problem and found a useful information about this issue on ipywidgets documentation

"""A text representation of the widget is printed if the widget control is not available. It may mean the widget JavaScript is still loading. If the message persists in the Jupyter Notebook or JupyterLab, it likely means that the widgets JavaScript library is either not installed or not enabled. See the installation instructions above for setup instructions.

If you see this message in another frontend (for example, a static rendering on GitHub or NBViewer), it may mean that your frontend doesn’t currently support widgets."""

So there is nothing we can do on static notebook.

p.s. Maybe this is more of a ipywidgets issue, as I see that the button widgets also do not render in a WYSIWYG way.

Yes, that was what I suspected (and afraid of). Thanks!

cc @eteq , how sure how much this would be a blocker for rendering notebooks over at notebooks.

Wait, I'm not sure you can interpret it quite that way, @pllim and @michiboo : when it says "for example, a static rendering on GitHub or NBViewer", that doesn't mean all static views don't support it... In principle as long as you can embed the javascript for the widget in the static view it could still work.

That said, a better/more stable approach is probably to build machinery that turns an ImageWidget into a regular Image upon saving or converting to the static view... I'm not sure how to do this exactly, but it should be possible. Perhaps that needs a separate issue though?

Should I re-open this issue then? Or should this be upstream somewhere in ipywidgets?

@pllim Thanks for the information!

@eteq Would it be better if we export the notebook to html using nbconvert? It will preserve the widget.
