Nope, it's not a new feature of publisher, sorry, we can't help with your persona but we can help with your template images.
Most of you know about the 'dummy' image approach to putting images/pictures into your templates. You insert a dummy image into the template and then in the properties dialog for the image navigate to the Web tab and use the following command:
This works great as long as the dummy image dimensions match or are of the same aspect. If not then you are going to get some interesting images at best. Not the best way to introduce your company to your clients with a whacky image on your invoices that looks only vaguely like your logo.
You have another option, that is to add a field in the template that will call the image in directly. Its a piece of XSL rather than a friendlier publisher expression but when needs must. Its fairly straight forward but must be embedded inside a formfield.
There is a width and height attribute that you can set if you wish but leaving them out will result in the image being brought in as is.
This will pull the graphic in via a URI, in this case a URL. Remember if you're pulling via a URL then ensure you take care of any proxy settings required to get out of your intranet.
