I was just browsing through the forum, and thought of something.
For the images, or news and translations, the date could be added at the subject so that everyone will know where and when it came from.
For example, if someone wanted to share a magazine, they could name the topic something like this:
[0903] Actors Style
I just thought of this because I was browsing some other forums at the same time and noticed how everything was structured and organised with dates etc.
