RapidWeaver Stacks add-on info:
Replace themes background image. Change background image on the fly! Drag, drop, enjoy. Add cool overlay patterns (dots, canvas, pattern), opacity.
Probably the easiest way to change a background image for just one RapidWeaver page. Maybe you want different background images for different RapidWeaver pages? Just drag the BackGroundFiddler Stack to your Stacks page and drop a background image to the BGF Stack.
You can even add two BackGroundFiddler Stacks to layer background images. The BackGroundFiddler Stack is used on this page as background for a Foundation webpage (Joe Workmans theme).
The BackgroundFiddler Stack has an option to add a nice image overlay. You get to choose between 20 predefined overlay effects: Black or white dots, perforation, lines, canvas, hessian, wood, and more. If that’s not enough just add your own custom overlay pattern.
Background image can be faded in and you can adjust image saturation, hue and sepia toning – and added a SlowScale (Zoom) animation.
Stack, responsive, background, image, overlay pattern.
