I took and edited a picture. It was for embbeding it in a forum like this one. For that I uploaded it on Facebook. Unfortunately it altered the image giving it a dirty appearance: I then uploaded it to Google Drive to see if it looked better. It did: Do you see the difference? So my question is, I edit pictures using PhotoShop CS6, is there something in the program that I can use so when I upload it to Facebook it doesn't give it that dirty appearance?
