very nice script!
I’ve been playing around with it for a few days now, changing background, tweaking styles, using classes etc… to suit my needs

One thing I found interesting was to take into account page scrolling when choosing the 0, 1 2 or 3 position dynamically. Here’s what I changed:

Original code:

var pos = 1;
if(this.options.fixedPosition == HelpBalloon.POS_DYNAMIC)
{
var offsetHeight = this.balloonCoords.y - this.balloonDimensions[1];
if(offsetHeight < 0)
pos = 2;

Modified code:

var pos = 1;
if(this.options.fixedPosition == HelpBalloon.POS_DYNAMIC)
{
var cso = document.body.cumulativeScrollOffset();
var offsetHeight = this.balloonCoords.y - this.balloonDimensions[1] - cso[1];
if(offsetHeight < 0)
pos = 2;

NOTE: I added the parameters into two area of the file (around line 218 after _lastBaloon:null, and around line 1152 after autoHideTimeout:0,)

=====================================================
2. Modify HelpButton.js to resize the imag
=====================================================
After:
var balloon = new Element(’img’, {
src: this.options.balloonPrefix i this.options.balloonSuffix
});
Add:
if (this.options.width != null) {
balloon.width = this.options.width;
}
if (this.options.height != null) {
balloon.height = this.options.height;
}

3. You may also need to modify/set the contentMargin parameter to get the margins to work (I haven’t had much time to play with this one, but hopefully this will help some of you)

may i know how to use the ratings?
i cant seem to understand the demo.
where to add those codes?
which images to use?
by the way, im using visual studio for my project
