You can create two types of links:
1.) Links from Text - Block the Text you want to make linkable > Click the infinity icon > paste the URL you want to link to.
2.) Links from Pictures
a.) Insert a Graphic: Insert > Image > Upload Image or Choose File already uploaded > OK
b.) When the Link window appears click the CHANGE link
c.) Save the page, then test the page - if something is not quite right, then restart at Step 2.
