Storing Images in PostgreSQL

i managed to store images uploaded in a MySQL database by using the field data type as 'longblob'.

However, when i use the same application on a PostgreSQL db environment, with the field( in which i store the binary data of an image) data type as 'text', and retrieve it, it does not appear...why is it so?

btw, i point to a file called, say, showimage.php, in which is found the <img> tag, whose src attribute is pointing to another PHP file called, getimage.php?imgid=1. This is the file that retrieves the image binary data from database.

oh yea, think i should be using the datatype 'bytea' for Postgres to store binary data. But it still doesn't work.

To load and store images on postgresql, as documentation says (http://www.postgresql.org/files/documentation/books/aw_pgsql/node96.html#using_large_objects), you need use field type OID and functions "lo_import", "lo_export" and "lo_ulink" to store, retrieve and remove objects...
