How to Override Post Titles

Hey Everyone,

I am using a plugin that creates a new post each time a photo is uploaded. However, what that does is use the photo's file name as the post title.

This isn't ideal and doesn't look good on the site. I was looking for a plugin or way to override any existing post title with a default post title of my choice. I am sure this wouldn't be able to change past posts but was hoping there has to be a way to do this for all newly created posts.

Thanks for any help you can provide!
