I uploaded a picture for my tour but on the webpage, it displays vertically, not horizontally. How can I change it?

It looks like you uploaded that photo directly from your smartphone. 
When uploading photos, your images may sometimes appear to upload "sideways". Our system does not rotate images automatically during the upload process. The reason your photo would appear this way is that the photo was taken by your smartphone vertically and the image file itself is in this orientation.
But you can easily rotate your pic immediately after uploading. There is a special tool for this - a red colored "circle with arrow" in the down right corner. Each time you press this button you will turn your photo 90° clockwise, so finally you can put it in the correctly visible position.

If you have any difficulties with uploading and rotating pictures please watch the tutorial video (in English) with some instructions here
When you are satisfied with your photo rotation and zooming press the green button ✅ in the same down-right corner and then SAVE at the bottom of the page with your complete tour!
Thank you for understanding!
