Operand type clash: nvarchar is incompatible with image?

Hi
Please check the data type of the column, is it image type or not.Also check you are sending the parameter in correct order.

The data types used to store images will differ between databases but, if you're using SQL Server, I'd use the varbinary(max) type.

There actually is an image type as well but it is going to be removed in future versions so it's best to use the above type instead.
