Javascript image url replacement
<p>I want to write a greasemonkey script/chrome user script that takes any images with a certain syntax and replace a section of the url and puts it back in the dom.</p>

<p>Namely I have a page full of thumbnails, e.g. www.example.com/small/randomstuff and I want to replace the imades with the equivilant www.example.com/large/randomstuff</p>

<p>How would I do this?</p>
