I am beginning to realize that people may be confused by the position and purpose of the Upload button for the projects and posts.
As I understand it, the Upload button is ONLY for pictures.
The Save and Preview buttons are for the editing of posts, etc.
The Upload button is too close to the Save and Preview buttons, and it's purpose can be misunderstood. I would suggest that the Upload button should be immediately to the right of the Browse button that selects your photos.
If that is not practical, there should be some other way to visually group the elements associated with a photo.
Just a thought.
