Have you been disappointment to take a perfect picture and then upload it here to the MOC just to discover it displays sideways or upside down? Yet it looks correctly oriented when viewed at its source.
The reason for this behavior was provided earlier by the software support folks. It is:
Most phones auto rotate the view for the viewer. If you take a pic in landscape orientation the pic will display properly regardless of the way you turn the device. The forum can't do that. Most phones default camera orientation is portrait - folks shoot a pic in the Portrait view and it always looks fine to them - they upload the pic here and it displays in it's default view (on it's side).
The solution for most folks to fix this is to open the image holding the phone in portrait orientation, and resave the image on their device. When they upload it here - it should behave correctly. Additionally. many phone cameras have the tools to rotate picture to the proper orientation.
I have found that if I take a pic in Landscape mode, it uploads correctly. If you take the pic in Portrait mode, it uploads rotated. I use a Samsung phone.
For now, we recommend you take your pictures in Landscape mode to avoid rotation issues.
I have found the following technique to be best for me. I upload the phone picture to my PC. Not only to save it in an album, but ensure the rotation is correct for the MOC.
It seems that most of the photo display tools on the PC will attempt to correct a rotated orientation. I use Window Explorer, the View set to big icons, to find pictures. W.E. displays the rotation as it will appear when uploaded to the MOC. But clicking on the pic, depending on the program associated with the JPG. usually rotates it to the proper orientation. Don't ask me why.
*IF* you are using Windows to store your picture (not a phone, tablet or Apple device), most viewers lie to you about orientation. The only one I have found to be accurate is the Windows Explorer view (icon) of the directory. If the display shows a rotated image, then it is rotated. Here is a picture of the Windows Explorer view of "My Pictures" directory.
Notice the two pictures of the number 1. One is rotated 90 degrees and the other in rotated 180 degrees. What I do to correct this is to Right Click on the file, find the "Open With" option and select Paint. Paint allows you to rotate the picture and then save it in its new orientation. Then upload the picture to the MOC and you will be good to go.
There may be other alternatives but I have tried most of them and I have found this to be the best method. YMMV
If you have a technique that works well for you, particularly with an Apple device (I have no experience with them) fell free to Post it here. Maybe it will help other members.
