Help mixing 2 MYSQL databases

I have 2 db running for me – thanks to some help here, I didn’t loose the first one entirely!

But I can’t find the images that were uploaded to the old db. The new one is working fine with new uploads, and posting fine. The posts from the old db just don’t have the pic’s / uploads anymore. I can see the links from the admin>uploads section, but there aren’t any files connected to them – get a 404 error.

Can someone explain how to fix this?

thanks
