MAX function

suppose the records in a table containing the records below :

inventbatchid       itemid     a2      a3       a4      PIC3            
PO10901                 AB0001    A       DX      20       c:\photo\abc135.jpg
PO10901                 AB0001    A       DX      20       c:\photo\abc13512321321.jpg
PO10901                 AB0001    A       DX      20       c:\photo\ac135.jpg

In this case, which record will be returned by "MAX" function ? Tks

select inventbatchid,itemid,a2,a3,a4,
 Tent,
 max(case typeid when 'ImgS' then pic else '' end) as 'PIC3',
 max(case typeid when 'sketchA' then pic else '' end) as 'PIC2',
 max(case typeid when 'sketchB' then pic else '' end) as 'PIC1'  
into #tmp3 from #tmp2
