You can do that if you'd like. However, if you rename some of them, you may inadvertantly remove them from the articles they were used on, since the articles link directly to their filenames.

Go to the photos section and check under the photos to see which articles they were posted in. You may also have to change the filenames in there as well for them to appear again.

But to tell you the truth, I wouldn't really go through the trouble.
