So change the function logo MoinMoin/theme/__init__.py:
def logo(self):
""" Assemble logo with link to front page
The logo contain an image and or text or any html markup the
admin inserted in the config file. Everything it enclosed inside
a div with id="logo".
@param d: parameter dictionary
@rtype: unicode
@return: logo html
"""
html = u''
# if self.cfg.logo_string:
if 1:
pagename = wikiutil.getFrontPage(self.request).page_name
pagename = wikiutil.quoteWikinameURL(pagename)
import random
pics=[u"http://xyz.de/a.png", u"http://xyz.de/b.png"]
logo_string= u'<img src="' + random.choice(pics) + u'" />'
logo = wikiutil.link_tag(self.request, pagename, logo_string)
html = u'''<div id="logo">%s</div>''' % logo
return html
MoinMoin/theme/__init__.py seems to be reloaded for each page (even in the desktopedition).
instead of
"if 1" you might want to introduce a configuration variable pics and check for "if self.cfg.pics" ...
Cheers,
Henryk
