Save image to SQL

Question

I am trying to save a greyscale U8 image to an SQL database. I have tried using both the "image" and varbinary(MAX) datatypes in SQL Express. In LabView I have used "IMAQ write to string", "write binary file" and, last but not least,  tried converting an image into a 1D array of U8 and then into a hexadecimal string. Each time I get an error message
ADO Error 0x80040E07  Exception occured in Microsoft OLE DB for SQL server. Operand type clash.
The VI I am using to insert data into the database table is "DB tools insert data". This seems to work well for numeric data so there doesn't appear to be a problem communicating with the database. But when I try to save an image then the error message shown above appears.
Does anyone have a possible solution to this?
Thanks in advance.

I have resolved this problem I believe. You don't need to convert the image to a string - you can use the imagetoarray VI and wire the array directly into the "DB tools insert data" VI. I have used varbinary(MAX) as the data type in SQL as the "image" data type is not recommended.
