Image in Top Feature….

I am trying to add an image to a text widget. The goal is to have about 5 different images in a slider in the top feature. I have tried copying and pasting the code “https://www.killam.biz/wp-content/uploads/2012/04/DSCN0004-e1333639197944.jpg” into the text area, but when I add it to the top feature and view the page the top feature just shows the title and the code, no picture. What am I doing wrong?
