you  mean  the  originals  inside  the  iphone?  or  the  original  copies  residing  within  the  first  computer  folder  you  created?  I mean the originals residing in the folder on the laptop
first  of  all,  
DrButz4U … do  not  delete  the  pics  residing  on  your  iphone … until  you  are  certain  the  pics  on  your  computer  are  good.  Good to know, but in this case, too late.  After I verified they got to the laptop OK, I deleted them from the phone.  Figured once on laptop, what would change them?
the  iphone  pics … they  default  to  jpg  when  pic  is  being  taken/shot? Don't know what they are on the phone, but once on the laptop, they had been transferred as JPG.
when  you  said  you  had  uploaded  from  your  iphone  to  your  laptop … how  did  you  perform  this  action?
- connect  the  cable  from  iphone  to  laptop's  usb-port
- opened  file-explorer
- scrolled  down  to  "iphone" (left frame)
 
- down-arrow  so  files  appeared  in  file-explorer (right frame)?
was  the  above  your  method? Yes, this is how I did it. I open Apple Iphone, then Internal Storage, then DCIM, then the folder with the photos.    or  did  you  upload  them  in  some  other  manner?  the  above  method  is  what  i  have  always  used.

and  when  you  went  to  disconnect  the  iphone  from  the  computer … did  you  go  to  win-10's  control-panel / devices  and  "remove"  iphone  device  from  the  computer?  from  what  i  understand,  this  is  the  safest  way  to  disconnect.  No, I just unplugged it.  I looked at the Safely Remove Hardware and Eject Media and it wasn't listed, so I just unplugged it.
now  then,  
DrButz4U … is  your  laptop  the  only  computer  you  tried  downloading  the  pics  from?  do  you  have  an  alternate  computer  at  your  disposal  in  which  to  download  a  couple  of  the  streaked  pics  for  testing  purposes?  
have  you  tried  opening  the  copy  with  win-10  "photos"  app?  and  win-10  "paint"  app?  and  your  favorite  internet-browser? Tried both and the streaked photo remained streaked.
how  old  is  your  computer?  did  you  upgrade  to  win-10 … or  is  win-10  oem?  it  could  be  the  graphics  card  or  some  graphic  setting  conflict.  which  brand  is  the  laptop?  which  iphone  is  it?
so … i'd  try  different  computer … also  the  above  method
(s)  for  copying  photos  from  iphone … see  if  this  resolves  the  situation,  
DrButz4U.
another  possibility  is  opening  one  of  the  images  in  win-10  "paint"  and  re-saving  the  *.jpg  image  to  a  *.png  image.  another  effort  would  be  for  you  to  rotate  one  of  the  streaked  images  within  file-explorer.  to  do  this … right-click  image  and  choose  'rotate'.  The png photo still had streaks and rotate didn't change anything.
with  the  above  methods,  do  the  streaks  remain?
that's  all  i  can  think  of  right  now,  sport.  you  might  also  wish  to  pose  your  question  on  a  venerated  iphone  forum … as  well  k
p.s.  thanks  for  sharing  the  pic,  
DrButz4U … helps  to  understand  we  are  on  same  wave-length.
