Best luck to your girl.
As for the photos, we are talking about two things here.
Dealerimaging as a photo/data collection company and also as a company that photoshops backgrounds.
The photo service is 90% their training and hiring process. If they have good people and good process they will do well for you.
The background photoshop that they do is very well done (at least the example that they show). It is not easy to do this and you can;t do it with a $8/hour person like the dealers think you can nor you can do it with a $300 PC from Costco like the dealers have! It takes good people with a good eye and steady hand, knowledge of several programs (image editing, upload, etc), some investment in hardware/software, and lots of patience.
We did this for a while and we found that the cost Vs the difference in results wasn't tangible for the average dealer in my markets. Of course remember what I always say: every market, every make, every inventory, is a world! So if you are the first in your area your cars may perk up tremendously when people see them in Autotrader or Craigslist.
