There is no such thing. All you could do is create an HTML e-mail, but many users won't even view it in that mode for security reasons and it may get filtered. Similarly, Flash-based content may get removed/ not show up. So at best, if you really want to get a clickable document, you could use a PDF file containing a link. but did i mention that the user can suppress those, too? Well, sorry, but you are SOL. You want something that for a million reasons nobodyy can give you. The best you can do, as always, is host your content on a proper website and send peopel a link to it...
Thank you very much. Unfortunately I figured there would be no way to do this.
The website idea wouldn't work for this client either. She just wants an invitation IMAGE that she can email and within that image woud be a clickable link. I guess the PDF route might be the best idea in this case. I'll have to ask her if that would be acceptable.
THANKS AGAIN !
Yeah, wouldn't THAT be nice. Unfortunatley, this person wants a clickable link ON the image itself.
