Replication with data type "Image".

Hi,

  When replicating data from the Publisher/Distributor to the subscriber, I was wondering what happens if there is image datatypes within a row thats being replicated?

  I know that the image path is stored in the row(but this is transparent?),not the actual image file,but what happens if someone modifies the image data on the publishing Server(changes/deletes/updates the image) - does this pull across the new image within the row when replicated?

Thanks!

If a row contains only the path to the image file, then the image file itself is NOT replicated by the SQL replication!!!!
What you need is a separated file replication implementation... Either you can implement it using OS built-in replication (Win2k), or need 3rd party tools.

Thanks,
What happens if the row contains image Datatypes,are they pulled across each time you replicate?
 
If you replicate a whole table containing image datatypes and text datatypes,will it pull ALL the images across,regardsless if there has been an update to the image?

This depends on the replication method.
If you use a snapshot replication, all data (including the images) will be replicated at every replication.
using a transactional-based replication will replicate only modified data, but you will need to update some other colums that the image/text datatype because those modifications are not included in the transaction log.
