I think you are in the right track...
I don´t use foundation, so i can´t help in this point.
If your responsive image solution is based in image versions ( maybe small, medium, large ) i think you can create the thumbs of each image:
For example: [[*imageField:pthumb=`&w=300`]] [[*imageField:pthumb=`&w=500`]] [[*imageField:pthumb=`&w=800&h=400&zc=1`]] **if cropping needed***
If you use pthumb cached each image will create only once and then stored, improves load speed.
Example:

I recommend you this website for testing speed:

By now i´m looking for a good image solution as you are, when i decide which one i will tell you
Quote from: mmcgee at Mar 18, 2014, 12:03 PMHi Sebastian: I am reading that article now in fact. Trying to decide between HIRSC and PictureFill. Ysanmiguel uses PictureFill. I just don't fully understand how to use pThumb in conjunction. I'm using Foundation 5. Perhaps their interchange is an option? But interchange seems to be set up for images that are already sized and stored, and the media query just determines which to grab and load.
So with pThumb do I just mark up all of the various sizes I want based on the media queries? So I have my list item for MIGx and a couple of options for the image TV (I have two because there is an option with a caption and one without. So for the various image sources, instead of them being _sm.jpg, med.jpg, etc, they would be :pthumb=`480`, :pthumb=`780` , :pthumb=`1224` or whatever I need them to be. and each would have a specific media query attached to them? Am I on the write track?
