First, consider that loading images (and files in general) into a database is probably bad regarding the performance. If at all, you should store them in a separate database...

Besides that, you need to read about the .AppendChunk and .GetChunk to write/read to IMAGE (and TEXT) fields in SQL Server.
Another way to do this is store the file location in the database and simply place image files on the hard drive.  As far as removing the file just remove the record holding the location and then use the kill statement to delete the file off the hard drive.
