I've mastered how to post photos on threads, but not on my gallery. How? Also can I set up folders within my gallery? So I can separate different topics?
Start by clicking on the 'Gallery' button in the top bar above.
Once that opens, there will be a center bar with options: Gallery Home, My Photos, My Albums, My Favorites, Upload Photos.
Click on 'My Albums'. Once that opens you should see a 'Create a New Album' item that you can click on. Once you create an album, it should show with some options on the right, like 'Upload Photos'.
Go to your Gallery and click on "Upload Photos", select the photos that you want to upload, and then "Upload/Submit". After that finishes click the "Process" and the photos should appear in your gallery.
