In your account, go to IMAGES (top right).
Where you see the “ALL IMAGES” tab (left side), click the arrow down, and it will open a list. Click the “+ New Album”
When you’re going to upload the images (right side, again), you can choose “Add to album”, just select the album you want and also the “resolution” (“Auto Resize” tab) you in which you want the photos to be ulpoaded
Hope this helps
