Picture turned sideways

I had replied to Tom's post on Blanchard holders and attached pictures of mine.
When I attached them, they were all upright.
A couple days later, when I opened the post, my first or the obverse picture was turned sideways.
Can anyone please tell me, how to turn it right side up again?
I right clicked the image and looked at every option and I tried everything I could, but no luck.
Thank you, Bert

Orientation is a bit of a mess with respect to uploaded pictures. When you take a picture with a device that knows about orientation, the correct rotation is saved in the EXIF data of the JPEG file. When you upload an image here, if it needs to be resized down to a conforming size (both # of pixels and file size), the orientation gets stripped out of the EXIF data. When your browser goes to view this image, there's no orientation data present, so it displays the image without rotating it. Sometimes, this means to rotation is wrong. I haven't played with it enough to know if there's a good way to fix or avoid the problem. There might be a phpBB extension that allows correction of the orientation, but I haven't looked into it.
