Lightroom has only the capability to connect to images on hard drives that are directly connected to the computer.
Can you expand this a little bit please?
Why is it that the dropbox showing in lightroom is only showing my very old photos and not all the recent ones i've loaded?
thanks for the help
The photos must be on a local disk (internal or external) or a networked drive for Lightroom to make use of them.
Photos in "the cloud" cannot be used by Lightroom. The cloud is not a local drive nor is it a networked drive.
If the photos that are stored on Dropbox are not showing on your local disk somewhere, this is a Dropbox issue, not a Lightroom issue. Once you can get Dropbox to synchronize local and cloud copies, then you should be able to make use of the local copy in Lightroom.
