So this is what I was able to make work in image.html.tmpl:
#if $show_plot
<img src="${plot_name}.png?v=${int(time.time())}"
alt="${plot_name}"/>
#end if
that results in this:
<img src="weekChargeWH.png?v=1698342767" alt="weekChargeWH"/>
I'll give your version a try and see if it works the same; which it does.
What's funny is that the public version
of all this web stuff already has the timestamps, but that's done with
post-processing as part of the publishing flow
to swap out the host names in the various hrefs before pushing the files
out.
Thx, Chris
