Problems uploading photos of Xyphosia miliaria

I added image files then clicked 'save' but no images appear on my post (sorry  - I made two posts by mistake in an attempt to get the images to show). One on occasion I could see the image files embedded in the Body text, but images still don't appear.

I've had problems before when trying to upload images, even though they are only 0.5 MB.

 

Can anyone assist please?
