Error: BFILE not exists when i insert an image file(.jpg)

Question

Hi,
i have created a directory
called sampl_dir as '/home/oracle/files'
i have an image file(.gif) and 3 pdf filesin the
directory.
i insert 4 rows in to the table using BFILE for all
the 4 LOB.
i get output in TOAD, where for all the pdf files, but when i select * from table.
for all the pdf files output says 'EXISTS' but for the image(.gif) FILE, the
output says 'NOEXIST'
I tried putting all the files in different locations
and tried giving different file owner, and group owner
but whatever permissions i set or wherever i put the
files, the output always says 'EXISTS' for pdf files
but not for gif file.
so i was thinking there is something got to do with
the format of the image file, or is there someother
way to select image from the table. i mean i thought
"select * from table" may be does not work for images
but it does work for text, pdf documents. am i right?
how do i solve this?
Thanks,
Philip.

Hi Kamal,
this was the plsql code i used to load image file and read the length. and it did not work
DBMS_LOB.LOADBLOBFROMFILE(v_dest_blob, v_source_locator1, DBMS_LOB.LOBMAXSIZE, v_dest_offset, v_source_offset);
DBMS_OUTPUT.PUT_LINE('Size of BLOB post-load: '||(v_dest_offset -1));
but now i modified the above as the following one shown below and it worked, can u tell what was the problem with the above code
DBMS_LOB.LOADBLOBFROMFILE(v_dest_blob, v_source_locator1, DBMS_LOB.LOBMAXSIZE, v_dest_offset, v_source_offset);
DBMS_OUTPUT.PUT_LINE('SIZE OF IMAGE FILE: ' ||DBMS_LOB.GETLENGTH(v_dest_blob));
i did the select query as u told for selecting the length and now it works and i am able to see the output length as 27342.
Okay Kamal, now is there a way that i can view a pdf file and image file after i select them from the table. i mean when i do a select query on the blob column, i only see result as "(HUGEBLOB)". BUT instead can i see whether what is the blob that is stored like whether it is a pdf or image and what is the name.
how can i actually see the blob file names etc.
Thanks,
Philip.
