Creates windows out of your pictures (JPG or PNG) which can be placed anywhere on the screen (they do NOT sit behind desktop icons). These pictures can be resized, have transparency and include a text label if desired. You can create desktop wallpaper using these pictures and a background wallpaper of your choice (resulting image is in JPG format). You can resize a window by clicking and holding your right mouse button when your mouse is in the bottom right vicinity of the window. Drag the mouse while holding the button. The picture is scaled when you resize the window. You can drag an image file (from Finder, for example) onto the window, or right-click on the window and use “New from file” menu option to select an image file. When you use the app for the first time a new, empty, window will be created for you. Original pictures that you use with the app are not altered, they are copied by the app. PLEASE NOTE: Disabling "Change Picture: ..." in the Desktop & Screen Saver preference panel (in System Preferences) needs to happen for some users in order for the change desktop picture feature to function. Also, windows will ‘lose focus’ when you click on another window. If you have a problem contact us, dont leave a bad review. We will always try to help.
