Signatures with Graphics

Question

I don't see how this problem is solved. I too am trying to input a graphic into a signature with no end-user joy. Whilst it works fine with Mail, my clients mainly use Lotus Notes/Domino. I too have Notes 6.5 for Mac.
The graphic does not display in the Windows / Mac versions of Notes, nor in MS apps. It works fine in Mail, but that is not what I need. Several of my Notes-based clients also use graphics in their signatures with no cross platform issues.
Any thoughts?

I tried various bogus URLs, but they tended to break things. The URL really does seem to matter--in Mail signatures at least. I think the crux of the issue is that, as you astutely observed, Mail converts the webarchive back to HTML, which means the in-lined images go bye-bye. So, unless the image is on a server accessible to the recipient, there's no way to include an image. If I were going to attempt anything further I think it would involve CSS formatting, with the image included as a background image, so it would degrade better in mail clients that don't display HTML.
That seems to make the in-lined content rather pointless where mail signatures are concerned. Maybe Safari uses it under the right circumstances, but I haven't yet figured out what those conditions are. Even if I delete the WebResourceURL key and string entirely and dump the cache, Safari continues to look for the image at its last known location. It looks for the HTML file too, but at least it is able to render the HTML anyway, from the information contained in the data node, one would assume.
So it looks like the webarchive file format really doesn't afford anything in the way of a solution for formatted mail signatures. I hate to say it, but I think the format Microsoft uses would be more appropriate for e-mail because it's essentially a multipart MIME message. Ironically, they only seem to use it as a web archive format for browsers, an application for which Apple's format seems more appropriate.
The ideal solution would be some kind of standard for encoding presentation instructions in vcard files that mail clients could either support or not, so people could just attach their vcard, and the recipient could take whatever actions their mail client supports at their pleasure.
