Just give this a try:
1) Go to the page where you have the screen shot.
2) Click on the image (your screen shot) and then click on the Link Symbol in the ‘Editor kitchen sink’ tab above the content tab. [Image attached below]

3) After the pop-up appears, give the link to which it should redirect to. [ image attached below].

Ticking on ‘New window’ option is optional.
4) Save the draft and test it in the ‘Preview tab’.
There is another way of adding this code in ‘Text’ editor. ( not in visual). '<a href="your link goes here"> but the above 4 steps are simple.
Hope this helps.
