I think a combination of I18N Search and possibly I18N Special Pages (although I don't know that plugin well enough)
For example with I18N Search you can make a displayed list of all your "projects", dynamically created. So if you create a new page with a tag (or you make it a subpage) then it will be automaticly listed in that search result (I18N Search can make predefined searches, so you only see the result of a defind search).
Possibly with I18N Special Pages you could make a custom page type with the thumbnail.
