Figures not showing in archived(?) blog pages

[revifr]

Several pages won't show images where the text clearly shows there should be one. Example links:

• https://www.darktable.org/2012/09/geotagging-in-darktable/
• https://www.darktable.org/2013/12/of-histograms-and-waveforms/

In the concerned pages, where the image should be there's code like:

<figure markdown="span" role="group">
![The gradient test image](grey.png)
<figcaption>*Figure 1:* the gradient test image – follow the link, download and play with it in darktable</figcaption>
</figure>

which shows up like

![The gradient test image](grey.png) 
*Figure 1:* the gradient test image – 
follow the link, download and play with it 
in darktable```
