Hello,
First of all, please consider if storing images in a sql server is a good decision. I do not know the project details, but generally it is wise to store images on the file system and store only the path or the name on the sql server.

I store images in the file system and keep just the path in SQL.  That way the users can modify the images directly without the need of a program.  It works great.
