I just created portugese versions of the Plone Banners/Button I did the other day and also created a Plone Marketing group on flickr. This is mainly for collecting all banners, ads, wallpapers etc. in one group for easy lookup. So if you have marketing material, please join the group and put it in. The portugese versions of the banners are also in there. You can find a slideshow below.
