Hello Sara, this is a very nice feature for home shoppers.  However, as a single/team agent user (no bulk upload) it is quite cumbersome to load photos one at a time.  We usually reduce our photos down to about 1200x800, and the other on-line sites we use, including our home MLS, will re-size to their maximums from there -- and still give us swift upload times.  Even with a current speedtest.net rating for uploads at 5Mbps+, I sometimes have a photo stall out when loading to Zillow.  Thus, if the Zillow upload interface for single user accounts can be addressed next, this will be a nice 1 - 2 combo.  Thanks!  John
