Does a large amount 'image' data affect overall SQL performance?

Recently we added a new table into our SQL2000 database specifically to store scanned in images of documents. This new table contains a PK field, a couple of datetime fields, a couple of char(1) fields and one 'image' field.

Before adding this table, the database size was approx 6GB. Six months after adding this new table, the database has grown to 18GB - 11GB of this is due to the scanned in images.

Would this new table affect the SQL performance with regards to accessing other data in the database that has nothing related to the new table?

If so, would moving this new table into it's own database be recommended?

Thanks
