Hello all
That the two images in question here were re-uploaded and the same
thing occurred would indicate the problem does not lie with the ODK
uploader but within the image itself.
It appears that the issue arises on smartphone cameras (Apple and Android)
when the image orientation becomes corrupted. Here are two easy fixes.
[1] In Windows: select Paint, File, Open (your photo image file), click Rotate Left or Rotate Right as appropriate (select "Flip Vertically" to turn the image upside down, or select "Flip Horizontally" to make a mirror image of the photo). Once the orientation is correct, whether or not you changed it, click on File > Save As > JPEG > accept or change the file name and location. This will set the image's default orientation as viewed, regardless of the original camera orientation.
On Mac: open Photos app > select File > Import >select file > Image in menu > Rotate Clockwise (or Counterclockwise) > File > Close or Share. You also can open the file in the Preview app > click Tools > Rotate Left or Right > File > Save.
[2] The image is rotating because you are saving the image in JPEG, if you save your image in PNG then the orientation will not change.
Just try this and re-post in this topic.
Hope this helps.
