Hi,  
I am trying to display a photo on the screen which is stored as binary  
data in  
MS SQL2000 database.here is what i have written in controller.

def photo  
@person = Person.find(params[:id])  
send\_data(@person.uploaded\_data,  
:filename=\>@person.filename,  
:type =\> @person.content\_type,  
:disposition =\> ‘inline’)

end

but when i goto [http://localhost:3000/person/photo/2308](http://localhost:3000/person/photo/2308)  
I get the following error.

private method `gsub’ called for #Array:0x47454c4

Does anyone know how do i correct this.
