With the recent acquisition of Picnik – online photo editing tools, now Google Picasa Web Album users can too edit photos online similar to services offered by Flickr.

As per Google Photo Blog:

A few months back we welcomed Picnik, the powerful online photo editor, into the Google family and today we’re happy to share the first of more exciting things to come.

Picnik’s rich editing tools are now integrated into Picasa Web Albums allowing you to experience them without ever having to leave your account. As long as you’re using Picasa in one of the Picnik supported languages, just click ‘edit’ from the edit drop down menu or from the new handy Picnik icon.

Have fun editing your photos.
