https://help.launchpad.net/ includes an http image.

[Samuel Bronson]

Wiki pages, such as https://help.launchpad.net/, are mixing HTTP and HTTPS content at the moment, which triggers annoying dialog boxes on Internet Explorer with every pageload (at least, that's what happens with the way IE 7 is configured on the computers at my school). (Kudos to the IE team for that, by the way, assuming this is actually the default behaviour; it's probably a much bigger risk than visiting a page with an expired or self-signed certificate ever was, and firefox is always complaining about that!)

But, anyway, it looks like at least the launchpad logo is served over HTTP, and maybe some other stuff, so I think you either want to change that, or let people browse the wiki with plain HTTP.

The only http asset I can see on that page is '<img alt="Creative Commons License" style="border-width:0;vertical-align:middle;" src="http://i.creativecommons.org/l/by/2.0/uk/80x15.png" />' That server appears to do https so perhaps this can be easily fixed by changing to https for that png; unless of course it will result in http renders issuing warnings ;).
