document how to have images side by side

[maelle]

• Not possible when generating images from R Markdown

• See https://roweb3-hugo.netlify.app/blog/2019/08/20/forensic-science/ there can be one caption per image and one for the whole caption.

{{< gallery caption="Figure 1: Two images of partial bullet scans. Were these two bullets fired by the same gun?">}}
{{< img src="/img/blog-images/2019-08-20-forensic-science/bullet1.png" width="50%" caption="bullet 1" >}} 
{{< img src="/img/blog-images/2019-08-20-forensic-science/bullet2.png" width="50%" caption="bullet 2" >}}
{{< /gallery >}}

note that if one is very keen on placement it's better to combine images into one. With the gallery format above, when the screen is narrow, images are stacked vertically so if you say "on the left" in the caption it makes no sense.

I'm assuming that we don't really want to encourage the gallery option...

Yeah probably just good for the editors to know if there is an obvious use case?
