My MLS has changed the real estate photography playing field. The number of photos allowed used to be limited to 25. They now allow an unlimited number of photos for each listing.
So for me, this is a great advantage, since my competition in this market typically provides only 25 or so images for their base service. I typically provide between 40 to 80 or more images depending on the size and value of the property.
I have received feedback here and on other forums from other photographers, that no one needs to see more than 25 to 30 photos online when shopping for a home. However, the feedback I get from agents and their buyers is the opposite; the more photos the better.
Yes, many MLSs these days allow an unlimited number of images. As I recall, the NWMLS in the Seattle area has had this feature for many years.
My personal opinion is that 25 to 30 images are more than enough to market any property very nicely. I rarely see more than 30 photos on listings in my market. I doubt that home buyers want to look at 80 photos. I sure don't! But the only opinion that matters is that of your customers. If they want to pay for your time to deliver 80 photos, go for it. Just make sure you are covering your time.
Update 4/14/2017: Andrew below in the comments sites a study done by a New York brokerage that shows that the sweet spot for the number of photos in their listings is 11-14.
