You can use in the adapter directive the locate attribute and perhaps
a trusted attribute like:

<adapter
    name="photo_or_somthing"
    factory="theFactory"
    locate="True"
    trusted="True"
    />

The attribute locate will proxy your adapter with a LocationProxy

The trusted attribute will make sure that the security proxy get 
wrapped outside the adapter, which means that you have trusted 
access to yur adapters method but every thing which is returned
from this methods get proxied. If a adapter is not trusted,
the method of the adapter itself get security proxied.
