How could I load image via a Form when it is in runtime by not using default block

Question

1. How could I load image from my local computer to the database via a Form when it is in runtime?
2. And how to display the image stored in the database on a Form ?
Thanks buddy ~
A nice member answered this question already, but I want to know how could I do it by using manual create block instead of using database item directly~
Could anyone help me pls~

Answer 1

This is the only way I know right now:
1) Create this table
SQL> desc av_data
Name Null? Type
BLOB_ID NOT NULL NUMBER(10)
BLOB_TYPE NOT NULL VARCHAR2(10)
DESCRIPTION NOT NULL VARCHAR2(25)
BLOB_DATA LONG RAW
2) On form create a button with this 'when-btn-prssed' tgr:
DECLARE
     v_dirname          VARCHAR2(255);
     v_filename          VARCHAR2(255);
BEGIN
     v_dirname := 'C:\';
     v_filename := get_file_name(v_dirname, NULL,
     'Bitmap file (*.bmp)|*.bmp|'                    ||
     'JPEG file (*.jpg)|*.jpg|'          );
     IF v_filename IS NOT NULL THEN
read_image_file(v_filename, 'ANY',
'av_data_image.blob_data');
     END IF;
END;     
3) Add this pre-insert trigger too :
:av_data_image.blob_type := 'IMAGE';
Sorry if this is not exactly the answer you're looking for.
