Hi and welcome at last!
To get to your favorites in the RIL, sign in and go to the RIL.
Right above the blue bar that says "Welcome to the Image Reference Library" you will see another blue bar.
That blue bar will have "a line that reads "My photos" (for photos you've downloaded to the library) and "My favorites" Just click on "My favorites" and they will be right there.
Please don't forget to credit the person who took the photo!
If you have any more trouble navigating, check out the threads pinned at the top of this forum, the links in the signatures of guides, mods and admins or feel free to ask here for help anytime as well.
Take care, looking forward to hearing more from you.
