How to: Configure the max text repl size Option (SQL Server Management Studio)
Use the max text repl size option to specify the maximum size (in bytes) of text and image data that can be added to a replicated column in a single INSERT, UPDATE, WRITETEXT, or UPDATETEXT statement. This option applies to transactional replication only. This option is ignored by snapshot replication and merge replication.
