The cascading protection feature has no effect on restricting image uploads to a specified filename. However, once the image is uploaded, cascading protection kicks in and fully protects the page. Example at meta: [http://meta.wikimedia.org/wiki/Image:WinXP_warn.png].
Like with permanently deleted pages, there are images which are simply placeholders to prevent uploads.
meaning this [http://en.wikipedia.org/wiki/Image:Photo1.jpg]?
Note sure exactly when this was fixed, but on my test wiki and on en wikipedia I cannot reproduce this, I get "protected page" warnings.
Yeah, it appears to work on Meta-Wiki too.
Seems to have been fixed then.

Still seems to be a problem on MW.org. See http://www.mediawiki.org/wiki/Image:MediaWiki_logo.png, which should be protected due to its inclusion on http://www.mediawiki.org/wiki/Project:Protected_titles/list Is this because the image is being pulled from commons?
The image isn't transcluded; it's simply linked. Try [[Image:MediaWiki logo.png|1px]].
It is included using standard template syntax: {{Image:MediaWiki logo.png}} 'What links here' for the image says: Project:Protected titles/list (inclusion) That seems like it's been transcluded to me, and is exactly the same as the other non-image pages in that list behave.
What's transcluded is the nonexistent image description page, not the image itself. Image transclusions are noted not on the "What links here" page, but below the image description (under the "Links" heading). That syntax transcludes most types of pages, but not images. Please try the syntax suggested above.
I just noticed that the image already is transcluded on the main page (which has cascading protection enabled), so this shouldn't even be necessary. What issue are you experiencing?
OK - well that worked, and achieves what I wanted. However it does raise the question as to why {{Image:foo}} doesn't protect the description page from being edited (even if it doesn't protect against new uploads)...
Re comment 11, I'm not sure what's going on there. It isn't included on the main page, and that cascade was never there before. It appeared when I went to check it after adding it to the protected titles list, but has now vanished again. Glitch? [[MediaWiki]] hasn't been edited since january.
1. I don't know why that syntax fails to protect the image description page. I just know that it does. :-) 2. I thought that I saw the image on the main page (in addition to the logo in the upper left-hand corner). Is it possible that someone edited one of the main page templates to include it (and then reverted)? Otherwise, yeah, I suppose that it must have been a glitch.
1. Worth logging a separate bug for? 2. Well, I thought that might be the case, but I can't see anything in recent changes. Maybe that's what it was though. Either way, it was transitory.
No, I wouldn't bother filing a bug report. The use of cascading protection to prevent page creation isn't an officially supported MediaWiki function; it's a kludge that I devised. With the existence of an alternative workaround, I see little point in asking the developers to fix a feature that they didn't even intend to include. :-)

Cascading protection does not cascade accross projects.
Interesting... I thought it was a kludge _I_ devised *grin* Re: Comment 17, I am aware that the cascade won't protect the image on commons, but it should stop people uploading a local version that obscures it, or from editing the page (we get a lot of test edits all over the place on MW.org).
"This page has been protected from editing, because it is included in the following page, which are protected with the "cascading" option turned on: * Project:Protected titles/list Return to MediaWiki." If there is a problem elsewhere, please open a new bug report which is specific to the problem experienced.
Brion - the cascading protection works provided you link the image using [[Image:foo]] rather than transclude it using {{Image:foo}}. The latter does not protect the decription page (which, imho, is a bug) or the image upload (which is, imho again, not a problem). As per the advice above (that this was an 'unsupported use case' I have not logged the issue. If you think I should log it then let me know and I will do so.
