Available in two versions CharityPro and Lite
Panoramic
Description
Version CharityPro
This is the charity paid for version whose basic function is as the lite version - to let the user set the current background/wallpaper picture as the screensaver picture.
To do this is simple. First time in the screensaver picture defaults to the background picture automatically. All you need to do is click OK and it's done.
A version is downloadable that instead of displaying the current background it displays a panoramic picture of a beach.
The visual effect is that when the screensaver is called the desktop icons disappear. As with any screensaver a touch of a key or the mouse and the screensaver is closed giving the visual effect of the icons being displayed again. In addition it lets the user choose any picture from the system and network and display it as the screensaver picture.
The screensaver can be any picture it does not have to be the background picture - they can be different.
Set any chosen picture as the background picture - i.e. choose the screensaver picture first then set it as the background.
Choose whether or not to display the screensaver picture file name.
Write a picture description and whether to display it.

What is CharityPro? - A minimum donation is given for the program. In that donation usually 60% will go to a default or user chosen charity - the set default is cancer research. The remainder is a donation to Screengold to cover costs. The user/purchaser can elect to pay more than the given minimum price in which case 70% goes to charity.

There are many extra and useful features compared to the lite version.
The screensaver picture can be displayed in four different modes. Three of the modes match the background display modes in the Control Panel settings - stretch, center and tiled; so particularly if the screensaver and background pictures are the same the screensaver display mode can match the background - e.g.  the background is tiled so also can be the screensaver. The fourth mode is panoramic.

PANORAMIC is the most useful extra mode . If the picture is panoramic, i.e. proportions are more than 4/3 width/height (normal screen proportions), then the picture will scroll to and fro if the stretched mode is chosen. If the picture width in pixels is more than the screen pixel width then the scroll will also be applied in center true mode. A description will not be displayed in this mode.
Many digital cameras have a panoramic mode and this display mode lets you see the full panorama as if you were scanning the view with your own eyes. If you set the same picture in Control Panel as the main background and set the mode to center then if the picture size height is the same as the screen height when the screensaver comes in the same picture will now be shown scrolled.
N.B. The display in stretch mode is somewhat system performance dependent and low specification systems may show abnormally if the proportions are very great (e.g. more than 3.5/1) or the file size is very large. The picture size is shown in pixels in the browse dialog top right after the  "Browse" button  or RH thumbnail is clicked.

In the settings window helpful hints are displayed when the mouse is over a settings feature. This can be turned off
In the main screensaver display a "Help fight cancer dragon" is shown as a reminder. This can be turned off except in the 30 day trial period.

The picture description can be multiline and the user can choose the font and font characteristics (color etc.) so as to best show up the description against the background of the picture. The description does not display in panoramic mode.
The description can be set to display for a set time in seconds - the description goes away the picture stays. The user can decide if the description should be shown again after the lapse of the set number of seconds. The user can also choose where on the screen in six positions to show the description.

When the "Set this picture as background" button is active;  if you have not turned on Active Desktop you cannot show "jpg" backgrounds, a button is shown to let the user automatically make a "bmp" format copy of the "jpg" picture file if you do not want to use Active Desktop (see Windows help about Active Desktop);.

The Settings window has an attractive default background which can be also user chosen.

Clicking on the background thumbnail picture will show the picture as the background to the settings window - so you can see how it would look as a background - click that picture to close it and return to the normal settings window.

Install hot corners, if not already installed, by clicking caption at top left in BackgroundShow Settings . Hot corners let you call the screensaver anytime just by moving the cursor to the screen  top left corner. You can also move the cursor to the top right corner and prevent the screensaver from being called. There are settings for hot corners by right clicking its icon in the system tray bottom right.

In the screen capture copy below you can see the Settings controls : - Most are self evident. In the real display a hint is displayed as the mouse is moved over a control - see example below.

The left arrow makes the LH picture the same as the RH one. The right  arrow the converse.

If you want no background picture to the Settings window enter "nil" in the "Choose picture file" dialog. To restore the original sky background enter "sky".
