You can upload assets to use rather than select assets already in the asset manager.
Select files (A) opens a window to choose an asset or assets from your computer or drag and drop assets onto the asset picker window.
Whether selected or drag and drop:
- a single asset is uploaded and inserted into the editor window or page you are editing
- multiple assets are all uploaded and you can then choose which one to use
If you are viewing an album then assets are automatically added to that album when uploaded.
