I want to create a HTML form where the user can upload an image file. This image file has to be stored in an ORACLE table. I am thinking about something like this:

: <form action="http://myserver/put_picture.exec";
: method="post"
: enctype="multipart/form-data">
: <input type="hidden" name="..." value="...">
: Picture_ID: <input type="text" name="..." length=5>
: Picture_File: <input type="file" name="...">
: <input type="Submit" value="Store Picture Now">
: </form>

Has anybody ever encountered this problem? Does anybody know some relevant URLs where this topic is described?
Any idea will be greatly appreciated!
