Bill in Cleveland says:
In Cleveland the MLS is taking photos from the Realtors at 2048 pixels wide then they the MLS knocks them down to 640 pixels for their use but when they send them on to Zillow, Trulia and Realtor.com they are sending the 640 resolution and not the 2048 res. I believe it is a software problem that is causing this, and they seem not to be interested in correcting the problem which most software techs that I know say it is an easy fix. What are other MLS's doing in this regard so agents do not have to go to all these sites, claim there listings and reload the high res photos. My big concern is they pay me to deliver high quality and resolution and the the MLS screws it all up. There is such a huge sharpness difference between 640 and 2048 res.
Yes, this kind of MLS photo mangling is classic. Previous discussions on this subject always raise similar complaints. There are a number of things that photographers and agents can do to minimize the MLS photo mangling:
These kind of problems have been going on for so long I'm afraid everyone has gotten used to it. I don't know any easy way to fix this kind thing.
