Clarity is basically controlled by the size of the file in Mega or Gigabytes.

Your pic is only about 30 kilobytes.

This for example is 10 times bigger at 360 kilobytes, but still crammed into the same size pic.

Did notice one of your images was labelled as a "Thumbnail", a small file to make a small image, usually in a gallery containing lots of other thumbnail pics.

Apologies, I swallowed a dictionary for Lunch.

Have a habit of chatting the hind legs of donkeys !

Like this one in fuzzy Thumbnail format I created in PhotoShop.
