After uploading your pictures, did you notice that some portrait photos in the system are displayed as landscape photos (image has landscape orientation)? It is possible that the note "this is a portrait format" is missing in your picture file information. Normally, this information is stored in the EXIF data of the image. Our system reads this data and uses the information to display it correctly. If this information is missing within the file, the system automatically assumes a landscape picture.
Please check your EXIF data. If the note "Portrait" is not saved there, please open your photos again in your image processing program, rotate them and export them to your hard disk (or simply save the pictures). Finally, upload the corresponding pictures again
