Code must look like this:

img src=https://live.staticflickr.com/65535/54215617158_80137abb22_b.jpg

Meaning "image source & your pics's URL", which you put it into your posting already.
Then enclose this line with this type of brackets, no empty spaces between brackets and the "img" and the "jpg", but one between img & src:

< ... >

et voila
