Обсуждение: data-type for image files

Greetings,

I am relatively new to postgres.

I  would like to know if there is a data type for  file such as image files.
In otherwords is there a straignt forward  way to  place references to
images-files in a postgres table.  I notice there is a network datatype (cidr
or inet).  If an image file is stored at host://someplace/image for example
can  this 'address' be used   as a datatype  (i.e.  a   pointers in the
table..... ?

I look forwrd to  suggestions.

regards

Your basic options are these:
1. Use a BLOB datatype to store the images directly in the database.
2. Use filesystem pointers to store the image in a file, which is retrievable
through your interface code.

For a variety of reasons, I prefer 2.  However, the BLOB approach as strong
adherents.  See the Postgres docs for more info:

Hello... I had a similar question, for use with jdbc.  If you're running postgresql version 7.2.1 (not sure if this
typeis fully supported in earlier versions), there is also the bytea type for storing binary data. 

See the followng link:
