Why Is My Picture Uploading Sideways After I Rotate It
E'er wonder why some photos look correct in some programs, but appear sideways or upside down in others? That's because at that place are two different ways a photograph can be rotated, and not every programme is on the same page.
The Two Ways an Image Can Be Rotated
Traditionally, computers have e'er rotated images past moving the actual pixels in the image. Digital cameras didn't bother rotating images automatically. And then, fifty-fifty if you used a camera and held it vertically to take a photograph in portrait mode, that photograph would be saved sideways, in landscape mode. You could then utilise an image editor program to rotate the image to appear in its correct portrait orientation. The image editor would motion the pixels to rotate the image, modifying the actual image data.
This just worked, everywhere. The rotated epitome would appear the aforementioned in every program…equally long equally you took the time to manually rotate them all.
Manufacturers wanted to solve this annoyance, and then they added rotation sensors to modern digital cameras and smartphones. The sensor detects which way you're holding the camera, in an effort to rotate the photos properly. If you accept an image in portrait mode, the camera knows and can act accordingly so you don't have to rotate information technology yourself.

Unfortunately, there's a small caveat. Digital camera hardware only couldn't handle saving the image directly in rotated grade. So rather than performing the computationally intensive task of rotating the unabridged paradigm, the camera would add a small-scale piece of data to the file, noting which orientation the image should be in. It adds this information to the Exif data that all photos have (which includes the model of camera you took it with, the orientation, and mayhap even the GPS location where the photograph was taken).
In theory, and so, you could open that photo with an application, it would expect at the Exif tags, and then present the photograph in the correct rotation to you. The image data is saved in its original, unrotated class, only the Exif tag allows applications to correct it.
Not Every Program Is On the Same Folio
Unfortunately, not every piece of software obeys this Exif tag. Some programs–especially older prototype programs–will just load the image and ignore the Exif Orientation tag, displaying the image in its original, unrotated state. Newer programs that obey Exif tags will show the image with its right rotation, so an epitome may appear to accept dissimilar rotations in dissimilar applications.
Rotating the epitome doesn't exactly help, either. Modify it in an old application that doesn't understand the Orientation tag and the awarding will movement the actual pixels effectually in the prototype, giving it a new rotation. It'll await correct in older applications. Open up that prototype in a new application that obeys the Orientation tag and the application will obey the Orientation tag and flip the already rotated image around, so information technology'll look wrong in those new applications.
Even in a new application that understands the Orientation tags, information technology's oftentimes not quite clear whether rotating an image will motility the actual pixels in the image or just alter the Exif tags. Some applications offer an option that will ignore the Exif Orientation tag, allowing you to rotate them without the tags getting in the way.
This problem can occur in practically any software, from a programme on your PC to a website or a mobile app. Photos may announced correctly on your computer but announced in the wrong rotation when you upload them to a website. Photos may announced correctly on your phone but incorrectly when you transfer them to your PC.
For instance, on Windows 7, Windows Photograph Viewer and Windows Explorer ignore the Exif Orientation tag. Windows 8 added support for the Exif Orientation tag, which continued into Windows 10. Images may appear correct on a Windows 10 or 8 PC, but rotated differently on a Windows vii PC.
New Software Almost Always Obeys Exif Orientation Tags
Thankfully, about applications now practise obey the Exif Orientation tag. If you lot're using Windows 10, File Explorer and the default paradigm viewer will properly obey the Exif Orientation tag, and then photos that come up from your smartphone or digital camera volition be brandish properly. Google'southward Android and Apple's iOS both natively create photos with the Exif Orientation tag and support it.
If you lot're using Windows 7, you tin make this problem become away by upgrading to Windows 10. If you'd like to continue using Windows 7, you may want to utilize another epitome viewer that obeys the Exif tags instead of the default image viewer.
The average website or desktop application should as well obey Exif Orientation, although non all of them practise. If a photo appears sideways when uploaded to a website, that website needs to be stock-still–but you can probably rotate that prototype on that website anyhow. Desktop tools for working with photos should also support Exif Orientation tags. If an application you use doesn't, you may desire to find a more modern application.
How to Ready Epitome Rotation for Older Programs
If this is a problem for you–especially on Windows seven–you tin can also utilise JPEG Autorotate, which uses the jhead command in the groundwork. This tool adds a quick right-click "Autorotate all JPEGs in folder" choice to Windows Explorer. Select it and the tool will examine all photos in a binder, automatically rotating them according to their Exif Orientation tags and so removing those tags. Use this tool when you import images and Windows 7 and other applications won't have a problem with them.
Mod smartphones and digital cameras have faster hardware, and then information technology should be possible for them to save photos in an already-rotated country instead of just applying the Exif Orientation tag. Unfortunately, the industry seems to have settled in Exif Orientation tags as the standard solution, even if they aren't ideal.
