Photos upside down

Not sure if anyone else has seen this or got a solution to it

many of my photos when viewed in the gallery app are upside down or on their side, if I look at the details they have an orientation of 90 (some have 180)

The photos that are wrong where taken with my SII, photos taken with camera appear fine

the SII, Picasa and another tablet I have displays the photos fine, but the Nexus is showing them wrong

anyone any thoughts on this

 

Thanks for that, just been looking at that, problem is when i do that it saves the updated photo in my downloads folder, the original doesnt get touched

if I do edit them on my nexus, will this mess them up on my other devices (picasa, g+, s2, vox tablet all of which currently display them fine)

just to add, as i missed in first post, all pictures are stored online in picasa and I just have the tick under syncing photos (so they are not actual stored on my nexus)

 

i hold it various ways when taking pictures

if i take a picture portrait, it rotates it by 45 degrees (shows fine in thumbnail view, rotated when viewing fully)
if i take landscape, buttons on the phone at the right it seems to be ok
if i take landscape, buttons on the left it is upside down (upside down in thumbnail and when viewed fully)

locking the device to portrait does work, but I have to turn the device around to view them

the gallery app on my S2 (ICS) and on my Vox (2.3) display the images perfectly they dont get auto rotated on these (also when viewed online they are correct)

puzzling

 

there is an orientation flag embedded in the photos, this doesn't show on my other tablets so looks like they ignore it and display the photo fine, whereas the nexus uses it and rotates the images wrongly

found a free picasa album viewer in the app store and this works fine, i dont need upload/editing, just viewing photos

shame the stock gallery app won't work as i want, i quite like it

thanks for your help on this
