Create campaign posts with images from the web.
This is the Mass Planner - http://www.massplanner.com/ extension for Chrome, you will need to have Mass Planner installed and running for it to be able to send the images to your campaigns. What it does is it extracts all the images from the page you are currently on and it sends them to your campaigns in Mass Planner, so can select as many images from the page as you want or simply select them all, after that choose where you want to send them, to the Facebook platform, to the Twitter platform or to the Pinterest platform and choose which campaign/board you want them to be sent and press the "Send" button.
You can use it on any site that shows a lot of images, like google images searches, flicker or other image sites.
You can enable advanced settings in order to get only images of certain sizes, either smaller or bigger images.
This extension will allow you to add images a lot faster to your campaigns in Mass Planner, all there's left for you to do is write a short comment that will accompany each picture when posted.
