Default Software to rotate upsidedown images

Pictures taken by Apple iPad MD513TA/T can not be rotated.

Over a thousand pictures have been taken by this iPad, but all upside down.

Some of the pictures have been copied/pasted to PC and have been tested for rotating by Windows Office Picture Manager.
The Office Picture Manager could display the pictures but its rotating function was nonfunctional to these pictures.

How to rotate the pictures taken by iPad? On iPad? On PC?
Or, and app for this special job?

Thanks.

Can't answer for the source of your pictures because mine are all taken with a straight camera but I use FastStone which is also recommended here.

Thank you.

Don't remember when or where, but I do have an impression of reading something
saying that the reason that Windows could not rotate the images was due to the fact that Windows could not or did not recognize the EXIF files of the images made by iPad.

If this is true, the images transported by any means from Apple iPad to Windows OS are images w/o EXIF files, and this was the cause for Windows being unable to rotate the images.

And if this is ture, can FastStome rotate the images?

Thanks.

I don't possess the appropriate device to check this out so you'll need to install FastStone and try it yourself.

FastStone has a portable version so you can try it without installing anything. It's the button to the far right on the download page.

It can definitely rotate images without any need for EXIF data. Perhaps what you're referring to is that Windows will automatically offer to rotate images for you if the relevant info is in the EXIF, although I'm surprised if Windows Picture Viewer is unable to manually rotate them - I have images here with no EXIF and the rotate function still works.

Like MC though I don't have the necessary devices etc to check that out.

It's a tricky issue Vicky12. I've experienced this occasionally.

According to Microsoft Support, the JPEG EXIF orientation flag is currently not supported by Windows Explorer or the imaging applications that ship with Windows. In order for images to display with the correct orientation, the camera must physically rotate the image, the image viewer application must support the EXIF Orientation flag, or the end user can manually choose to rotate the image 90 degrees and save it. Note also it says that the EXIF orientation flag is considered unreliable because it is not widely supported, and double rotations can occur in the scenario stated.

There's also a note at the end of this page on Apple Support saying that when importing photos from your device to a Windows computer, some photos may appear to be rotated incorrectly. Some third-party photo-management software for Windows displays iOS photos with the correct orientation without having to rotate the images.

Regardless of the JPEG EXIF orientation flag, I think photos can be virtually rotated using Windows Explorer or other software. Try listing your photo files in large icons using Windows Explorer, right-click a photo or photos and select 'Rotate clockwise' or 'Rotate counter-clockwise' from the context menu and see if that helps. Check also the properties or attributes of the photo files are not set to 'read-only'.

However, virtually rotating photos without correcting the EXIF orientation flag may complicate the issue of double rotations as in the scenario mentioned above.

It is interesting to note that Windows Explorer in Windows 8.1 seems to have supported the EXIF flag. It displays correctly the photos I snapped using the iPad. But Windows Explorer in Windows 7 does not support it.

I find that I have to hold the iPad with the volume up/down button at the top/left (i.e., in landscape with the Home button on the right) to take a photo in normal orientation. Holding the device in any other orientation will have the photos shown abnormally using Windows Explorer in Windows 7.

The good news is, in my test, when you use Windows Explorer (in either Windows 7 or 8.1) to rotate a photo, it updates the EXIF flag accordingly so that other apps that support the EXIF flag can show the photo correctly.

Note: The orientation of a photo can be checked using programs such as Windows Explorer (in the 'Orientation' Details column) and Opanda IExif. They however show the orientation of a photo in a different way:

Windows Explorer - Orientation Opanda IExif - Orientation
Normal top-left
Rotate 90 degrees left-bottom
Rotate 180 degrees bottom-right
Rotate 270 degrees right-top

For reference, these articles list how apps and services handle the 8 EXIF orientation values:
