$wgUploadUrl is set incorrectly on this site to "images" instead of "/ProjectWiki/images".

This reliative URL is resolved by the browser from /ProjectWiki/index.php ok, but not by anything else -- your code snippet simply adds a "/" on the front, making it "/images". (Note this will also fail if $wgUploadUrl is a fully-qualified URL, such as on sites which serve their images from a separate domain.)

I think you mean $wgUploadPath instead of $wgUploadUrl. I found nothing about $wgUploadUrl at http://www.mediawiki.org/wiki/Category:Upload_variables

Adding the starting slash if not existent was only a quick and dirty workaround, because at first the problem seemed to be a missing slash in the middle of the URL. Maybe no good idea.

The Wiki sysop told me he had to set $wgUploadPath="/images" (or "images"?) to get another extension to work. I thought this would cause no problems: Uploads go to the new directory http://robertfant.com/images (or better, one of its subdirectories) and files are retrieved by getURL() from the same place. Seems not to be true. New uploads still go to http://robertfant.com/ProjectWiki/images/<subdir>/subdir>/... Why?

Just for sake of clarity: What is the difference between $wgUploadPath="/images" and $wgUploadPath="images"?

What will the Wiki sysop have to do that uploaded files go to the same place where my extension will retrieve them? Does it help to change both $wgUploadPath and $wgUploadDirectory?

How did you know so quickly about the content of $wgUploadPath without access to LocalSettings.php? Maybe there is a Special:XYZ page showing the content of all $wgXYZ variables.
