Just something I've been noticing and actually I saw a thread about how there have already been fights over this...
I would recommend this wiki adopt a policy of specific naming when it comes to images. For example, the image File:Ben.png has a quite lengthy history of re-uploads and version-warring. Consider yourself in this situation: you come up with an episode named "The Guardian." You go make a page for it but discover that there already is one. You then decide to make your page The Guardian (Young Plumbers) so that it is more specific and people realize that it is different than the other page. Likewise, this should be done with images. Naming an image "BenInOmniverse.png" is better than naming it simply "Ben.png"
Just to emphasize, consider this: A page that everyone uses can be shared, such as Ben Tennyson, meaning that everyone has some of their own content in it. However images cannot be shared, meaning they are singular and others must be uploaded separately. You wouldn't have edited a page called "The Guardian" and replaced it with your content, so why should you do that with images?
A final note. While I am in support of an extreme system with no shared pages (ie, the Ben Tennyson page would be a disambiguation page while every series would have its own Ben Tennyson (Series Name) page), I don't feel that it is possible on this wiki, given two things: (a): it would require a lot of people to transfer their content from shared pages onto their one ones, and (b): it would over crowd the wiki, creating too many new pages. Then we would reach 30,000 by the summer.
Anyway, that's all I have... Admins, please consider this :)
