@Fabric Lover, I have rotated one of your images
using
Lunapic. It's a bit long winded but as you can see it does work. The steps are:
1. upload your image to Lunapic;
2. to rotate, click on the 'Edit' tab and select 'Rotate image' which is towards the bottom of the list;
3. in the 'Angle' window, make the degree 90 and then click the green arrow that faces right;
4. scroll to the bottom of the screen and click 'Imgur';
5. copy everything in the 'Image URL' window;
6. use the link to re-post the adjusted image using the little Mona Lisa icon in reply.
The above is a practical demonstration of how it should work. I selected a vertical image and rotated it to the horizontal.
