The code for this is in One Click. This is a little standalone scriptlet that does one thing. It fades images in and out by incrementally changing their opacity. The controls are simple: Commands !fade --in|<seconds> !fade --out|<seconds> !fade --in --all !fade --out --all <seconds> = optional fade time (default 1 second). --all = affects all graphics on the current page. Examples: !fade --out Fade selected to 0% over 1s !fade --in|3 Fade selected to 100% over 3s !fade --in|3 --all Fade in all graphics on page over 3s Graphics fade over 20 opacity increments but you can edit this in the code if you want it smoother. All affected graphics update simultaneously. Demo:
