I have an schema with an Rich Text Field that has embedded images.  The source that the DWT renders looks like this:

    <img src="tcm:84-40483" tridion:href="tcm:84-40483" tridion:type="Multimedia" tridion:targetattribute="src" border="0" alt="">

After Default Finish Actions does its magic, the tag turns into a regular image tag with a relative path in the src attribute, i.e. it bakes it like this:

    <img src="/en/Images/myimage.jpg" />

I need to render an absolute image path for certain DCPs for a third party email campaign app to pick up.

I can certainly achieve this by writing a Image Link Resolver TBB that grabs the base path from the Publication's custom metadata and concatenates it with the relative URL that Tridion spits out.

I am wondering if it's possible to achieve this some other way, hopefully via configuration, similar to the configuration available in cd_dynamic_conf.xml where you can specify the `host` attribute.  I fully understand that this config is on the CD side, while the image path is baked by the Publisher.

My question in two parts is:

 1. Is it possible, and if so how, to make the defalt Link Resolver TBB to render a dynamic binary link to an image (instead of a baked img) and then control URLs via the cd_link_conf.xml and cd_dynamic_conf.xml configs on the CD side?
 2. Or if 1 isn't possible, is using a custom link resolver TBB to make the image path absolute the best way (via concatenation), or are there other options available?
