ShoeBox Gallery auto rotates picture 
Author: T B.On my Page, I created a Text Object with link to the "ShowBox Gallery". Added pictures that are corrently oriented in my fille, but ShowBox keeps rotating some 90 degrees ccw. How to override this?
On my web page, I have this:
2017 Birth
Gallery => ShowBox Gallery => list of pictures.
Picture on computer file are oriently correctly. Add pictures to the list and some picture are rotated ccw. Open the picture on the computer with Windows 10 Photo Viewer, rotate it, save it, check that the picture has been rotated, then add it to the list, and it still get rotated again to the "same" wrong direction. Tried several times using the Photo View to rotate the picture to other orientations and ShowBox again rotates it to the same orientation each time.
thanks

Try Irfanview (free) http://www.irfanview.com/
Open the picture/s rotate and save as. I have found many Windows photo viewers change an attribute in the viewer rather than the image.

You are correct. Used what I had installed, rotated one picture as a test, added it to the gallary, and it was as desired.
Used AVS Photo Editor and I suppose most photo editors will do it right.
THANKS
