Normally, the photo was taken "lying down," and the correct orientation was tagged in the orientation
tag of the EXIF .
The problem is that the photo is actually recorded "lying down" depending on the device (most commonly cell phones and tablets), and it is only "noted" in the Tag which is the correct orientation.
The consequence is what you noticed in your application. In some viewers, the image appears in the correct orientation, however depending on the browser it will appear "lying down," because the EXIF tag is ignored in certain situations, and in some cases not.
The solution is to open the images in some graphical application, and correct the position. Preferably deleting the EXIF orientation to avoid further ambiguity.
This is an EXIF-oriented image. Click on it to view out of <img>
, and test on more than one browser :
A good test is to save on the PC and check the thumbnails, and open in different software, to see how inconsistent the tag behavior is.
-
In IE11, for example, it always appears lying down.
-
In Opera 34 appears lying on the post, but in separate tab appears standing. Already in Opera12, it appears lying in any situation.
-
In the Windows 7 viewer and thumbnails, it appears lying down.

This same photo that was saved in Windows 7 and is appearing lying down, when opening with Photoshop CS6 appears.
