Adding Scripts to others' web pages: a few thoughts

There could be problems doing things like document.body.appendChild when there DOM hasn't loaded yet.
Therefore you need to do things to watchout for that

< body onload = "customfunction()" >

or put script tags right before body

or window.onload =

or window.attachevent("onload",customfunction)
window.addeventlistener("load",customfunction,false) //or true I dont know

What about large images etc. that you dont want to wait for

another thing to research is the defer attribute of the script tag

another thing to research is the DOMContentLoaded

http://developer.mozilla.org/en/docs/Gecko-Specific_DOM_Events
"Fired on a Window object when a document's DOM content is finished loaded, but unlike "load", does not wait till all images are loaded. Used for example by GreaseMonkey to sneak in to alter pages before they are displayed. "

what about document.write

Flash Ball example slow in some cases

The ball example that I did is slow in IE7 on my windows vista.
When I open the swf in the browser on IE and on Safari it is also slow.
In Firefox,opera,safari it is fast when embedded in a page.
When I open the swf in the browser on firefox 2, it starts fast and then goes slow.
In opera when It is embedded in a page it is fast, and when I open it in a browser it is also fast!
