XHR Failed Loading

Hi there,
I've been trying to set this module up properly for a few weeks now, and I don't seem to be making any headway. Apart from the fact that it apparently doesn't play well in overlays and modal windows, there are two main sticking points:

1. The use of (deprecated) call-time pass-by-reference (fancy words coming from a non-php dev) resulting in an error message for php <5.4 and outright breakage (as in WSOD) in anything greater. It appears to be coming from the file_chooser_field.inc, line 30.

2. The image imports don't just seem to work (at least for instagram and dropbox). Both result in the following message in the browser console:

XHR failed loading: ""
c.fn.extend.remove @ js_UWQINlriydSoeSiGQxToOUdv493zEa7dpsXC1OtYlZU.js:116(anonymous function) @ js_L_t_KN0eNhyJj4QE07d7Lq8uSxw6PF_Nn0WARHuO2tQ.js:24

All my testing was done in the latest version of Chrome (as at this writing anyway). I really want to use this module - everything else carries a bunch of weight in the form of dependencies and configs. Cheers and good luck
