Help! Best practice for organising an image bank

Hello, 

I'm a designer within an e-commerce business. At present there is no formal system for organising our image bank. 

Some team members within sales/marketing are using libraries of images uploaded to Lightroom. This works really well for them as they find it easy to quickly select, edit and download images. Our files are cloud based, so it also means they aren't having to sync lots of files to their hard drives. 

I am more used to having all files stored in a central location and then browsing through bridge. I also really like being able to tag images to make browsing easier. My concern is selecting and downloading from shared libraries on Lightroom could get messy and also slow down my workflow. 
I am also worried about having lots of different versions of the same file floating around, although currently the team is small so it's not an immediate concern. 

My boss is happy for me to make my own system but ideally it would be nice to have a solution which worked for everyone. Although Bridge is my comfort zone, I am trying to be open to other ways of doing things, so I'm also curious to know what the current best practice is... I've been using Bridge since my first job 12 years ago and I know things change and people find better ways of doing things! 

Thank you!
