copy image to clipboard in wxHtmlWindow

Hi,
I have a wxHtmlWindow that has images on it. Currently, it opens up a
splash screen on a left click and a popup menu on the right click.
What I'm trying to do is add another menu on the popup menu to copy
the image to clipboard. How do I do this? Is it possible?
Thanks for any help

This is what it kinda looks like:

class MyHtmlWindow(html.HtmlWindow):
    def __init__(self,*args, **kwargs):
        html.HtmlWindow.__init__(self, *args, **kwargs)
        self.right = False
        self.left = False
        if "gtk2" in wx.PlatformInfo:
            self.SetStandardFonts()

    def OnSaveAs(self,event):
        dlg = wx.FileDialog(
            self, message="Save file as ...", defaultDir=os.getcwd(),
            defaultFile="", wildcard="*.png", style=wx.SAVE
            )
        if dlg.ShowModal() == wx.ID_OK:
            path = dlg.GetPath()
            cont = True
            if os.path.exists(path):
                dlg = wx.MessageDialog(self, 'The file already exists.
Overwrite?',
                               'Overwrite?',
                               wx.YES_NO | wx.ICON_INFORMATION
                               #wx.YES_NO | wx.NO_DEFAULT | wx.CANCEL

wx.ICON_INFORMATION

                               )
                if dlg.ShowModal() == wx.ID_YES:
                    cont = True
                else:
                    cont = False
            if cont and os.path.exists(self.link):
                shutil.copyfile(self.link,path)

    def OnCellClicked(self, cell, x, y, evt):
        self.m_x = x
        self.m_y = y
        self.link = None
        if evt.GetButton() == 1:
            self.left = True
            self.right = False
        if evt.GetButton() == 3:
            self.left = False
            self.right = True
            self.saveAs=wx.NewId()
            wx.EVT_MENU(self,self.saveAs,self.OnSaveAs)

            self.menuMenu = wx.Menu()
            self.menuMenu.Append(self.saveAs,"&Save As")

        sel = html.HtmlSelection()
        if isinstance(cell, html.HtmlWordCell):
            sel = html.HtmlSelection()
        super(MyHtmlWindow, self).OnCellClicked(cell, x, y, evt)

    def OnLinkClicked(self, linkinfo):
        if self.left and not self.right:
            print ('OnLinkClicked: %s\n' % linkinfo.GetHref())
            self.link = str(linkinfo.GetHref())
            splash = MySplashScreen(str(linkinfo.GetHref()))
            splash.SetTransparent(220)
            showed = True
            splash.Show()
        if not self.left and self.right:
            self.link = str(linkinfo.GetHref())
            self.PopupMenu(self.menuMenu,(self.m_x,self.m_y))
