Select the Insert menu and then click More Gadgets.
Find and open the Insert menu in the Google Sites Editor. You will be able to see a list of gadgets you can add to your site, like Links, Tables, and Images. Click on the More Gadgets option. This will let you add editable tools like POWr Photo Editor to your site.
The Gadget manager will be visible. Click Add Gadget by URL. Copy and paste this URL into the box. Click on Add to finish.
Now that you've added your new, editable Photo Editor Widget to your Google Sites page, you might want to resize the Widget. Use the different options in the window to select the height and width of your plugin. If you'd like, you can add a border, title or scrollbar to your Photo Editor Widget, but we don't advise it. There is more editing control through the plugin itself.
Set up POWr Photo Editor
Visit your live Google Sites website and click the Settings Icon in the top right corner of the Photo Editor Widget.
In the POWr Editor, click Import Existing Photo Editor, find Photo Editor- and click Copy.
