Consider a situation: you find a groovy image on the web and you want to share it with your Facebook friends. A lot of Facebook users will first download the picture to their computer and then upload it on Facebook. But do you know that you can upload images from the web without downloading them first?
Right click the image you want to upload and select Copy Image URL.
Now log in to your Facebook account and select Add Photo/Video. Click on Upload Photo/Video.
Click Choose File and in the dialog box that appears, paste the URL of the image you want to share on Facebook and click Open. It will automatically upload the image to Facebook. Give it the caption you want and post it to your timeline.
That’s it. Much easier than downloading the image first.
