Is there a wiki setting that I'm missing: on Finnish Moodle we have a wiki in which I can't add external images with the format []. However, both on test.moodle.com and here on Using Moodle (Developer Wiki) these images work. Which checkbox is unchecked and where, that would allow this?
Tried this link and it displays without problem in wikis with a variety of settings. So I can't help you solve the problem directly, however, the following may help you troubleshoot it.
When I use "Check links" on the page where the image link is situated it comes up as "Dead".
