The little light turned on for most of this. Except for 2b:
or b) add it to the project in the application server target and
use the WOImage tag if I want the app server (ie Webobjects or
Tomcat) to serve it up (understanding a slight performance penalty
is applied).
No. You can add it to the Web Server target only; its location
will be resolved by the WOResourceManager/WORequestHandler, and
served by the web server.
Why would I be adding it to the Web Server target scope if I wanted
it to be served from the Application Server? Wouldnt I then be
telling the project the the image is going to be found in my HTTP
server and not the webobjects application server?

I learn best running through samples that apply what was said:
Case 1: If I have a static image (ie a company logo) that is
shared across multiple applications, my best bet is to simply
refer to an existing storage location such as a company web site
and use the HTML img tag.
You can do it this way, and it probably is the best approach.
Case 2: If I have a static image (ie an Application Specific
Logo), I can a) store it in a web server location, use an HTML img
tag and refer to it if I want the web server (ie Apache HTTP
Server) to serve it
Yes, you can.

No. You can add it to the Web Server target only; its location

Case 3: If I have an image that changes dynamically, add images to
the project as in b above and use the WOImage tag.
Web Server target, and use a WOImage with filename binding set to a
key in your component.
Can I use a WOImage tag and refer to a static location(ie http://
www.someserver.com/images/someimage.jpg) and then modify the url
(ie http://www.someserver.com/images/someimage2.jpg) through my code?
Yes, works fine.
WOImage supports bindings of filename, src and data, each of which
can be bound to keys (instance variables or methods) in your
components.
