I agree with Zephid. Access supports only 2GB per database and then you're done. And if you are warehousing bitamaps or tiffs, you can chew that space suprisingly fast. Personally I store all of our imaged documents in a special directory and name them with a numeric primary key. Then in use vba to load them as needed into forms. This concept will work for word documents as well. Simply use the on_current event to load the image/document into an unbound control.
In the alternative you can make the image/doc not load until the user clicks a "view" button. This will perform faster obviously.
