The changes get a thumbs up from me.
The only problem I can see is keeping those pic weights to a reasonable size. Apart from that issue, which I'm pretty sure won't even be an issue, this just seems a logical next step.
I've been feeling quite good about currently using 24 pics per freesite, and now everyone else will be doing it! Dammit!
Just got to go with whatever the current rules are and adapt as necessary.
