Here are instructions for adding links to photos:

When you are in edit mode, click on "HTML" on the editing bar, Find your image code, it should look something like this:

<div style="display: block; text-align: left;"><a href="https://sites.google.com/site/friendsofthekaw/life-on-the-kaw/StillLifeOnKansasRiversmall.jpg?attredirects=0" imageanchor="1"><img src="https://sites.google.com/site/friendsofthekaw/life-on-the-kaw/StillLifeOnKansasRiversmall.jpg" border="0"></a></div>

The highlighted area is what you want to replace.  It always comes between <a href=" AND " imageanchor="1">
Cut and paste the url from wherever you want to image to go to when you click on it and paste it in.  Let me know if you have problems.

This is what the code looks like after with the replaced url highlighted:
<div style="display: block; text-align: left;"><a href="http://www.kansasriver.org/content/nancy_marshall" imageanchor="1"><img src="https://sites.google.com/site/friendsofthekaw/life-on-the-kaw/StillLifeOnKansasRiversmall.jpg" border="0"></a></div>
