But this breaks when you use virtual hosting.
I try to always do one of the following:

a) give a relative path and let acquisition deal with it...
e.g. <img src="images/whateverimage" />

or (preferred)

b) call a method that gives a good result in all circumstances,
e.g.
<img tal:replace="here/images/whateverimage" />
or
<img tal:attributes="href here/images/whateverimage/absolute_url" />
or
<img tal:attributes="href here/images/whateverimage/absolute_url_path" />

etc.
