Gsub error

Rails
1

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
I get the following error.

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

Does anyone know how do i correct this.
