var someString = "http://example/uploads/files/full/images/image.png";
var path = someString.match(/https?:\/\/example\/(.+)$/)[1];

http://jsfiddle.net/Squeegy/QwHsC/

// matches http or https
https?

// matches :// since you have to escape slashes
:\/\/

// matches the domain name
example/

// captures the path all the way to the end of the string
(.+)$

If you want to use a more comprehensive library for this sort of thing in future (ie rather than constructing/requesting specific regexes as you need them), you could take a look at something like this:

http://blog.stevenlevithan.com/archives/parseuri

In which case,

parseUri("http://example/uploads/files/full/images/image.png").path

would return

uploads/files/full/images/image.png

Parsing a URL is better than regex hacking a URL, when possible.

@AlexWayne Yes I agree... but I guess you get the green tick because you answered the specific question as asked! ;-) Must admit I'd probably hack out a regex rather than go out of my way to incorporate a new lib, if it were a one-off where I knew the format of the URL wouldn't change etc...
