use relative urls based on the document root

[kaluzki]

Meanwhile we use relative urls in our shop environments relative_urls => true. IMO it could be the default behaviour.

But actually relative urls (without leading slash) don't work properly:

Loading the image

<img src="images/example.jpg">

from seo url http://shop/category/product.html instead of http://shop/index.php?id=<id> will end up in 404 Not Found http://shop/category/images/example.jpg

Possible solution

return (tinyMCE.activeEditor.settings.relative_urls) ? "/" + tinyMCE.activeEditor.documentBaseURI.toRelative(url) : tinyMCE.activeEditor.documentBaseURI.toAbsolute(url);
