Picnik is a powerful online editor for editing photos and this service was acquired by Google some time back. Google has now integrated Picnik to Picasa Web albums, which means you can easily edit your Picasa web album photo in Picnik. Picnik’s rich editing tools are now integrated into Picasa Web Albums allowing you to experience them without ever having to leave your account. You can easily access Picnik by selecting Edit in Picnik option.
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. Picnik opens inside Picasa, so you dont have to leave the web page to edit photos.
You can add effects, stickers, touch ups, frames, text etc and do basic editing with Picnik. Integration of Picnik with Picasa is a very nice move for all Picasa web album users, now they can easily edit images without having to download them.
