Problem

Enable the opposite of imageused to find pages which do not use a certain image. Eaxmple:

<dpl>
category=Foo
notimageused = File:Test.jpg
</dpl>

This would return pages in Category:Foo which don't use [[File:Test.jpg]].

I couldn' t think of anyone who might need something like NOTimageused ...

Could you send me a working example of a SQL statement (maybe a derivative of the statement produced by DPL when specifying the imageused clause) ?

Extension:DynamicPageList (DPL), version 3.2.1: Warning: No results.

NOTimageused comes in handy for image maintenance when you use your wiki more like a content management system or when simply all pages in "Category:XY" should use File:XY.jpg.

"imageused=x.jpg" what did you test there? I mean the opposite. Find out which pages in a category don't use a certain image.

<dpl>
category=Test Images
imageused=Bob Ross.gif
</dpl>

This returns [[Muha Test]] and [[Muha Test 2]], but I'd like to have the other page in Category:Test Images as result: [[User:Subfader/P1]] cos that doesn't use [[File:Bob Ross.gif]] --Subfader 21:23, 4 February 2010 (UTC)

I understand perfectly what you want. I asked you to figure out how an appropriate SQL query would have to look like (because I do not have time to figure that out). I gave the query for "imageused" only as a starting point as I thought the inverse query might look similar. If you come up with a working query I will teach DPL to produce that query. --Gero 21:32, 4 February 2010 (UTC)
