[Plugin: Google Picasa Viewer] error on activating widget and no albums

I’ve just installed the plugin and on moving the widget to the sidebar, I get the following error on the public page: ” Fatal error: Uncaught exception ‘Zend_Uri_Exception’ with message ‘Invalid URI supplied’ in /home/xxxx/domains/xxxx.com/public_html/wp-content/plugins/google-picasa-albums-viewer/zend/library/Zend/Uri/Http.php:156 Stack trace: #0 /home/xxxx/domains/xxxx.com/public_html/wp-content/plugins/google-picasa-albums-viewer/zend/library/Zend/Uri/Http.php(186): Zend_Uri_Http->__construct(‘https’, ‘//picasaweb.goo…’) #1 /home/xxxx/domains/xxxx.com/public_html/wp-content/plugins/google-picasa-albums-viewer/zend/library/Zend/Gdata/App.php(644): Zend_Uri_Http::fromString(‘https://picasaw…’) #2 /home/xxxx/domains/xxxx.com/public_html/wp-content/plugins/google-picasa-albums-viewer/zend/library/Zend/Gdata.php(221): Zend_Gdata_App->performHttpRequest(‘GET’, ‘https://picasaw…’, Array, NULL, NULL, NULL) #3 /home/xxxx/domains/xxxx.com/public_html/wp-content/plugins/google-picasa-albums-viewer/zend/library/Zend/Gdata/App.php(875): Zend_Gdata->performHttpRequest(‘GET’, ‘https://picasaw…’ in /home/xxxx/domains/xxxx.com/public_html/wp-content/plugins/google-picasa-albums-viewer/zend/library/Zend/Uri/Http.php on line 156″

What am I missing?
