If you would like an image added to a text (editor) to open a link you will need to add some HTML code to the image tag to make sure that clicking on the image doesn't just open a larger view of the image (the current default for an image).

You can fix this by adding the "nowrap="true"; to the <img> tag.

So, briefly:

Import your image to the text editor. 

Open the HTML editor by clicking on the HTML icon in the toolbar.

Add "nowrap="true"; to the <img> tag.

The result should look something like this.

Example: <img nowrap="true" src="https://yourwebsite.com/theimage.png" border="0" width="100%" />

This way the link from the surround <a> element will be opened instead of opening the image in a new view.
