I use the photobucket app.
upload at the bottom, choose existing photos, select photos and start.
Moving into a new folder isn't as easy as on the PC but can be done. select my album then photos. click on photo and then lower left share icon, move, and select folder (one at a time) Have not found out how to do multiple photos on the app.
to create a new folder select my album, albums, edit, + symbol, name your folder.
