grant create any directory to a;
grant create any library to a;
create or replace directory photo_dir as 'e:photo';
create table photos (blob_column blob);

declare
a_blob blob;
a_bfile bfile := bfilename('PHOTO_DIR','flower.jpg');
begin
insert into photos values (empty_blob()) returning blob_column into a_blob;
dbms_lob.fileopen(a_bfile);
dbms_lob.loadfromfile(a_blob,a_bfile,dbms_lob.getlength(a_bfile));
dbms_lob.fileclose(a_bfile);
commit;
end;
/

user reports to display the image. Change the file format of the displayed columns in the reports to image.

hi,

you can use the following method also:

First create a table:
id - number
img - blob

in the fmb, you can create a data block from the table.
make the item for img as "Image Item".

Then you can display the image by simply giving an execute_query on the data block.

to read an image from a file to a form, you can use the forms built-in READ_IMAGE_FILE

PROCEDURE READ_IMAGE_FILE (file_name VARCHAR2, file_type VARCHAR2, item_name VARCHAR2);
