Free space to the rest of the database from a single table

Hi,

I have a table where we did a compression the JPG that make up the LOB data. This made the table about 70% smaller. However, I can see that the unused space for the table is 56GB vs 41GB of actual data in the table.

I'm trying to release that unused space so that the space is not assigned just to this table but available to the whole database. I do not need to shrink the physical files.

Is this something that can be done?

SQL Server 2008 SP3 is what I'm running.

The index size is only 624K, the majority of the data is the LOB.

Is there a property of the table that is telling it to keep this much free space to itself? Or some other factor?

(we have Merge replication in use which makes it impossible for me to simple recreate the table, I really need another option).

Thank you.
