For INSERT, it's pretty straightforward.
INSERT INTO dbo.Table1 (ID, Pics)
VALUES (1,{Image BLOB})
You get into real problems when trying to use UPDATE, though. Generally speaking, you can't UPDATE blob fields (such as text and image). You have to use READTEXT and WRITETEXT, which are very unwieldy, especially when working with images.
As a frequently used solution, try storing your images outside the database. Then, just store the path to the image file in the database. It's MUCH easier to work with, and much gentler on storage/backups/etc.
