So other than rather tiresome forum-lawyering, is there a satisfactory answer to this question? I just did a search on Google and came to this question, and did a search within the forum and only found this thread
http://forum.dokuwiki.org/thread/2471 which doesn't answer our question.
I know there are ways to do it using PHP, but frankly I know next to nothing about PHP. I've googled various PHP scripts which describe how to do it, but I've no idea where to put the scripts, or how this works with Dokuwiki.
Anyone have any helpful suggestions, or pointers as to where we could look for an idiots guide on how to implement image watermarking in Dokuwiki? I imagine a lot of us would want to protect our work and images using watermarks.
