Welcome to CakesDecor! Your cakes are amazing!! I’m not sure you can rotate a picture once you have posted it, but I think Michel can. If he doesn’t see this note in forums, you can sent him a private message.
You need to rotate them before you post them. If you are posting a picture without changing the orientation in an editing software (any one), your pictures will be in the original orientation… SO change it before posting! Hope this helps :-)
And welcome to cakesdecor!!
Michelle you would need to rotate the pic in a photo editing software first before uploading. If you are on a pc you can simply open the photo in windows viewer and use the arrows at the bottom to rotate it in the correct direction.
