MIGX Fancybox-images with seperate placeholders in Richtext-Content

Hi to all,

I have read and tested the MIGX with fancy box for may image gallery and it works fine.

However the negative side is by adding placeholders like [[+img.0]] , [[+img.1]], [[+img.2]] manually on Richtext-Field.
I think it i would be better and to became user friendly if we can do this automatically inserted or no more adding to placeholder.

Thanks
