Oh dear Alf, that incident at Tesco brought a smile to my face.
I know it is not funny but I am not surprised in this heat you forgot your wallet.
I would have paid for your groceries if I had been there

After all someone did it for me once, and wouldn't give me their details so I could repay them.
If someone is short of a few bob at the till, I'll make up the difference.
Hugs for you.
Now your photo.
I am making a guess from the way you phrase your question, '...as to how I rotate the picture in this app,' that the photo was the correct way up when you downloaded it to this site? But yet it comes sideways when you have downloaded it.
Now my iPad sometimes does this, and has me demented because it was the correct way when I took it, and it was the correct way in the photo album and it downloads to wherever I put it, into sideways.
Nothing you have done wrong, it is some blip/bug in the iPad. (By the way this never happens with my android devices).
There are two things you can do.
The first is to download your sideways picture which is already on this site like
@jjraak (I presume) and I did, back on to your iPad with this downloaded photo. Go into edit for that same picture, and go into the box which has an arrow round it. Keep clicking on that box until your photo is the right way, and then download it to your post. It will be the right way now. And you then get rid of the wonky picture. This is one way.
Now, you don't know in advance if the iPad is going to put your picture sideways. There is no warning. But if I have taken a batch of photos which all go sideways when I download to a site. And they are all the right way in the photo album, I am in tears, so frustrating because I cannot retake them. But one trick I found, is to go into edit for that batch of photos, for each one, and shave a tiny bit off each photo, so basically go into crop, and take a minuscule bit off each photo, and then save. Now you can download them all and they will come up the right way when downloaded on to the site.
I hope this is of some help. Ask me again if you need me any more in this.
