wget does a good job of pulling down prerequisite files, but it cannot detect image paths inside a JS file. I need a regex to scan JS files for any image paths it finds.
These paths would generally be nested as follows:
$img1 = "foo/bar.png";
$img2 = 'foo/bar.jpg';
$img3 = "{'myimg':'foo/bar.png'}";
I need a regex which will be able to pick up the whole image path inside the quotes, but sometimes nested inside a json string, or otherwise encoded... essentially, matching a whole image path by detecting just the existence of the extension (jpg|png|gif).
