bypassing xss filter

Is there any known way to bypass filter on img form: Filter add http:// after src=, after that I can add JS, but it doesn't work because of http. Hope I explain it ok. Tnx

I find another way ;)

Um, I'm not quite sure what you're trying to say…try listing some examples and whatnot.

I know this article it is realy useful. I found another option to complete the same thing, but I am still interested in old question (I am not really sure it can even be bypassed). Example: I can add for example:

javascript:alert(document.cookie)

into BB img tag (with some variatons). It create output in html:

<img src="http://javascript:alert(document.cookie)">

As you see it add http:// which disable javascript, so I am asking for a way to bypass this.
