I checked the element (image of it, you can copy and paste to see in full size):

• As you can see, the size does not matter, as it gets adjusted to fit the page.

• When you saved the pic, it was saved as size: 640 x 0

Now let me try (after I turn your photo):

Mine does not show the size...

Try to use your original ad do this:

1. Open a comment here.
2. Open the Windows Explorer and highlight the photo title (first check it is turned correctly). Carry it across into the comment box and release it. It should upload. Did it do so correctly?

I was just wondering - when making the post, do you use the Markdown Editor or do you use the HTML option? I've never used the Markdown, so if it is that, then I must admit, I've never used it and do not know how to use it.

By the way - I love the photo. I grew up in East Africa and some of our beaches used to be this pure white.
