Once a picture is in a frame on a publication page, you can alter it to support your message. You can use tools on the Picture toolbar to recolor the picture, increase or reduce contrast, change its transparency (to show text and objects behind it), and add a border and a background.
In the examples in the picture, we used the Picture toolbar to do the following:
We added a colored border around the picture frame in the top picture.
We recolored the bottom picture and added a colored background to the picture frame.
