No idea what you are trying to accomplish (lack of details). A resource an Image object can be referenced through its URL, same as in HTML.

@zopyx My method

def get_portrait_url(self):
    super(ToolbarViewletManager,self).get_portrait_url()
    member_tool = api.portal.get_tool('portal_membership')
    user = api.user.get_current()
    user_id = user.id
    portrait = member_tool.getPersonalPortrait(id=user_id)
    return portrait

How will its template looks like? <img src=""'/>

If the method returns a URL the template will look like this:

<img src="${view/get_portrait_url}">

In one project I have the following method so you probably miss the call to absolute_url method aswell:

    def get_user_portrait(self):
        portal_membership = api.portal.get_tool('portal_membership')
        portrait = portal_membership.getPersonalPortrait(self.user_id).absolute_url()
        return portrait

If you are trying to override the toolbar viewlet manager check this documentation:

can you show us the zcml code you used to override the viewlet?

Viewlets and Views usually have two parts: 1) Sometemplate.pt and view.py. It looks like you have not defined 'get_portrait_url' the right place.

I would make an addon with plonecli and add a viewlet. That way all the code you need will be made for you, and you can just add the code suggested.

Note: Your view.py (or viewlets.py) file MUST have

def get_portrait_url(self):
    return 'something'

for you to use

${view/get_portrait_url}

In you viewlet template

UPDATE: I now see that you have posted another question, looks like you want to override a viewlet.
