Question

I have a webpage and a F-Share button. On clicking this button, an image uploaded by the user is posted on facebook. I tried to initially use javascript to set the ‘picture’ property with image data from fileupload and it didn’t work. So, my guess is that, Facebook does’nt save the images to its server but instead fetches them and displays them from the url we provide. Is that the case? If not, please guide me how can I use the image from fileupload in the ‘picture’ property?

If you mean the thumbnail that is posted on the FB wall when sharing a page, you can control what image is used by defining some META tags. Here are some examples from the docs:

Look under “Sharing Rich Media”
