The wiki Christipedia has no longer via the function Insert > Images and media access to the images of Wikimedia commons, only to the images already used on the wiki.
Yes, it works again. Today, after John's post of Oct. 16, I tried about six times to find a random image, of which one time it failed. When I reported the incident, I had tried several times. And also on days later on it did not work.
The connection with the image database of Wikimedia is much better now, but, seeing the one incident of this day, it seems to be a bit unstable.
