How to insert a JPG image in a column of type "image" in sql server 7.0 ??

Question

hi all,
I have a table with 2 columns.
First col is of "Name" and second col is of type "image" .
I am using sql server 7.0 on window 2000.
now i have created table. I want to insert a jpg/gif image in its 2nd column.
How can i do so ? and how i can i read the image object after insertion ?
I am using 2nd col of type "image" and NOT Binary or varBinary.
Any idea will be highly appreciated.

AlwaysJavaHi,
Below are some excerpts from my program.. which was doing image insertions and retrievals also.. I have included the image insertion and retrieval portion.. retrieval can be done in more than one ways.. one of them is given.. for very large images, u can read chunks of data from the input stream and write it to the disk. for smaller ones , the given methods work very well..
I tested the program with jdk1.4.0 and aveConnect3.0 driver. on an
SQL server 7 machine from my box running windows 2000... and it worked..
Im not still sure if this is the optimised way.. there can be other more optimised methods..
hope this clears your problem..
cheers,
