To add text to an image: And create a water mark.
First click the "T" tool.
2nd click the top of your image & hold & drag, a text box will appear.
3rd Type away: choose color & font & hit the "enter" key to move the text down the image.
4th use the "T" Arc tool, top right of your screen.
This will allow you to angle the font wear you want, if you do not want it horizontal.
5th I changed the opacity to about 60% & flattened & saved my image.
