- * @fileoverview Detection for whether the user has Picasa installed.
- * Only Picasa versions 2 and later can be detected, and only from Firefox or
- * Internet Explorer. Picasa for Linux cannot be detected.
- *
- * In the future, Picasa may provide access to the installed version number,
- * but until then we can only detect that Picasa 2 or later is present.
- *
- * To check for Picasa on Internet Explorer requires using document.write, so
- * this file must be included at page rendering time and cannot be imported
- * later as part of a dynamically loaded module.
