You have two problems here. First, JSP scripting variables are not available
from the JSTL expression language. Second, you can't (yet) use JSTL
expressions outside JSTL tag attributes.
You'll need to set an attribute, like this:
<% pageContext.setAttribute("prov", prov); %>
and then access it like this:
<img src='<c:out value="${pageContext.prov.photoPaths[0]}"/>'
