IMGSIZER and MSM - member photos

I am using imgsizer to dynamically resize AUTHOR photos on display - not a dealbreaker if this doesn’t work because there aren’t that many different photo sizes. But I’d sure like to be able to figure this out.

On my original site, this is the code:

{if photo_url}
{exp:imgsizer:size src="{photo_url}" width="85" alt="{screen_name}" id="{member_id}" class="left"}
{/if}

It works like a champ.However, on the second site, it does not work at all. You might expect this, since author info is not site specific. However, we have gone into the server settings and made it so that calls to the author photo directory on site 2 resolve to the same directory on site 1.

Like this: http://www.site2.com/images/member_photos/ resolves to: http://www.site1.com/images/member_photos/

So now, all actions performed by site2 should affect the site1 /images/member_photos/cache directory. However, nothing is being written to the cache directory and nothing is being read. I’ve turned on template debugging, but don’t see any obvious errors. It just says that imgsizer has returned data.
