I use NWiki on 1.9.5+ (and I loose my old wiki contents... so...)
But now my problem is how to include pictures in a wiki page?
Using htmleditor or nwiki editor have the same behaviour:
I can see the picture in the preview but not in the view mode.
I try with internal picture locate in the .file.php of the course and with external pictures locate on other websites.
Is it a problem of parser or some right adjustement in the moodle configuration?
I had the same problem. For some reason Moodle is really picky about how the files are named. It appears that the file names have to be all lowercase with no spaces (newfile.jpg, not new_file.jpg or NewFile.JPG).
For some reason, when I changed the directories (just for good measure) and file names all to lowercase, no spaces, the images worked again.
Hope that helps.
