As for the photos, that's what I did but it obviously doesn't work for me
For Lee:

I get it working if the image is hosted on another site/forum with using "From URL" AND with the "Retrieve remote file and reference locally" box uncheked. In this case I get an IMG tag + the URL of the image in the editor. If this box is checked, I get "error: Upload failed due to failing writing temporary file".

example with this image hosted on my website.


I have my answer about the board from Doddy who had some photos from 2020 when he did a mod for me.
Nice !
