If you haven’t worked in GPC recently, then better check it —-now, when you add a photo to Google Page Creator, you'll see new options. You can now crop a photo, rotate it, change the brightness, mix it with another photo, change the contrast, reduce the colors or sharpen the photo. Basically you can apply simple effects from your browser.
Also, every page that’s created in Google Page Creator can be easily accessed from a mobile phone, as Google redirects it to the transcoded version, the same way it does with the search results. Of course if you manage to enter the long URL correctly.
