MSSQL and blob field


I am using blob field in Interbase. I would like to convert interbase
database to MSSQL.
I cannot do it. I do not know how to store blob fields.
My problems:
    1, I would like to store binary data  into blob field. What kind of
field do I have to declare in MSSQL database?
     Binary, VarBinary ?
     Image - I can load only Bmp files into it.

    2, How can I  load data into the field.
        I can store data into Interbase field, but I cannot MSSQL.

    3, I have seen a lot of question about this, but there is not a full
example, why ?
