converting from byte[] to image format

Hi,

  I am using web services to retrieve one record from database. here in this
  record there is one image field.In web service, the record is converted
  to xml document and sent to client

 when i send this record to client thru webservice , this photo is
 converted as byte[].

 to check before giving to client, i checked my webservice. for that i
 took  a new .aspx page  and i retreived my record in to dataset and
 binded that to gridview. In gridview, I could see my image in byte[]
 format

 I want to change this byte[] to previous image format in my asp.net page.

 I am unable to change. I searched in google , I am unable to solve my problem.

 please help me..
