unable to read data in image format

 Dear All,

My requirement is to display employee image along with data. for this i have created below query

select f.employee_number,f.full_name,f.national_identifier,f.date_of_birth,f.original_date_of_hire,f.person_id,f.person_type_id,i.image 

from Per_All_People_f f,per_images i

where f.person_id = i.parent_id

---and f.person_id = 76---1207

and sysdate between f.effective_start_date and f.effective_end_date

but problem is that, at the time of execution report fails with subjected error.

we have already changed file format property to "image" but problem remain persists. any idea?
