Damn, I am really unconcentraded lately. :D

Ok, I just changed the code so that I get the url which was used to download 
the image. If multiple images were combined into one, then only one of those 
image-links will be used.

Now when I click on the "Copied From" link in Dolphin it will display that it 
does not know the protocol.
That is why I looked at the Resource via the nepomukshell [1] and here I see 
the url yet I wondered when I did _not_ find the referer url.

This is what I am using:
Nepomuk::Resource copyEvent = Nepomuk::Utils::createCopyEvent(mImageUrl, 
destUrl, QDateTime(), mWebsiteUrl);

your blog entry. Great tool that is! :)
