Add blobs into a database table

Question

How do I add blobs (images) into a table using portal forms? For example, in the table:
CREATE TABLE DEPT(
ID NUMBER,
NAME VARCHAR2(45),
LOGO BLOB
I need to add the logo for each company via portal forms. I also need the user to see it.
Thanks,
Marcelo

Try the following:
Create a table to store images:
CREATE TABLE mySchema.myImages (
id NUMBER,
name VARCHAR2(50),
image BLOB
Create a Portal Form component based on the table above. This Form will allow uploading images via a GUI interface. Images may also be queried and displayed in the Form.
Create a Procedure as below to retrieve images at in PlSql:
Create or Replace Procedure mySchema.showImages
(v_id IN NUMBER DEFAULT 1) -- Default image (ID=1)
AS
v_img BLOB;
BEGIN
SELECT image INTO v_img
FROM mySchema.myImages
WHERE id = v_id; wpg_docload.download_file(v_img);
END showImages;
Ensure EXECUTE privileges are granted on "mySchema.showImages" to other schemas (or PUBLIC) as needed.
Execute Procedure in a PlSql Item, Dyanamic Page....
BEGIN
mySchema.showImages(2); -- Display image (ID=2)
END;
