Unable to view higher resolution pictures in forms

Question

Hi All,
There is an existing custom form, which has a table data block consisting of header_id,BLOB(image) fields.
there are "upload_image" and "remove_image" buttons.
when i press upload button a window opens and i select an image and press OK it is uploaded into into table.
The code is as below
plist := GET_PARAMETER_LIST (:SYSTEM.custom_item_event_parameters);
GET_PARAMETER_ATTR (plist, 'OPENDIALOG', ptype, pvalue);
uploaded_file := pvalue;
v_chr_path :=
SUBSTR (uploaded_file, 0, INSTR (uploaded_file, '\', -1)
- 1);
v_chr_name := INSTR (uploaded_file, '\', -1) + 1;
GET_PARAMETER_ATTR (plist, 'LASTDIR', ptype, pvalue);
set_last_dir (pvalue);
SET_CUSTOM_ITEM_PROPERTY ('FILE_DIALOG', 'GFMAGENT', fnd_web_config.gfm_agent );
gfm_access_id := fnd_gfm.authorize (NULL);
SET_CUSTOM_ITEM_PROPERTY ('FILE_DIALOG', 'ACCESSID', TO_CHAR (gfm_access_id) );
SET_CUSTOM_ITEM_PROPERTY ('FILE_DIALOG', 'UPLOADFILE', TO_CHAR (NULL));
SELECT file_id INTO v_num_file_id FROM fnd_lob_access WHERE access_id = gfm_access_id;
g_num_header_id := :main_block.header_id;
transfer_file ------>database procedure to upload image
(o_errbuf => v_chr_err_buf,
o_retcode => v_num_retcode,
o_num_imag_size => v_num_image_size,
i_num_access_id => gfm_access_id,
i_chr_button => g_chr_button,
i_chr_area => g_chr_area,
i_num_header_id => g_num_header_id
execute query;
transfer_file has query as
EXECUTE IMMEDIATE ' UPDATE '
|| i_chr_area
|| ' SET '
|| i_chr_button
|| '= (SELECT FILE_DATA FROM FND_LOBS FL,
fnd_lob_access FLA
WHERE FLA.access_id = :1
and FLA.file_id =FL.FILE_ID ),
last_update_date = sysdate
WHERE HEADER_ID = :2'
USING i_num_access_id, i_num_header_id;
image are loaded to database table
I am able to view images of resolution less than 720X600 (approx) in front end.
But I am  unable to view higher resolution images.
Can Some one help me how can i View higher resolution images?

Have you read the Restrictions in Form Builder help under READ_Image Built-in?
