Benny, when you are on the image page, look directly to the far right just under the artist's name. You will see the little boxes/icons for Facebook, Twitter, etc. At the far end of that row, you will see a heart icon. Just click on that and it puts the image in your favorites. Just for your info, if you hover your mouse over each icon and let rest for a second or so, you will see text for what each icon represents. Hope this helps.
I see you are brand new to FAA. Welcome! I wish you the best.
