Assuming I understand the explanations properly ---- about images coming out sideways ------ it's due to the way that the image is stored in the camera (eg. ipad camera device, or android camera device etc) - or rather ----- stored in the image data file.
With most basic digital cameras (with no tilt sensing features etc) ---- if you hold the camera in the regular way (horizontal/landscape orientation) and then take a pic, then the image gets stored in that way - landscape.
And when you then tip the camera 90 degrees, and then take a pic, then the most basic digital camera will still store the image in 'landscape' format ----- which is expected. So viewing this image on any computer taken by the most basic digital cameras would appear 'sideways'. This is for basic cameras.
But ----- with more fancy cameras --- cameras with tilt-sensors etc ---- when you tilt the camera 90 degrees, then the camera will still store the digital image in LANDSCAPE format (as usual). HOWEVER, the camera will then add an extra piece of information to the image data file ----- such as adding a 0 or a 1 or 2 or a 3 value (which is nothing but extra information). If no tilt, then the piece of information would remain '0'.
That extra piece of information (eg. depending on whether it is 0, or 1, 2, 3, etc) can tell your image viewing software which way to ROTATE your captured image, so that the viewed image (in your image viewer) will look exactly the same as when you FIRST captured the picture.
That is, if you did not hold the camera in the regular horizontal orientation when taking the picture ----- then the photographed image will be stored as a SIDEWAYS image; and the extra piece of information added to the file can be a 1 or a 2 value (depends on whether you rotated 90 degrees clockwise, or 90 degrees anti-clockwise). And if the camera was held upside down, then a '3' value could be stored with the data file.
Now ---- if the orchidboard software wasn't designed (or written) to use these orientation values, then uploaded images that were taken in a 'portrait' orientation could easily come out 'sideways'.
That is, if the orchidboard software ignores (or cannot read) the orientation information (which is part of an image file), then that is most likely the reason for 'sideways' images.
