I agree with the other agents comments here as well. The photos posted on the Internet are a potential buyers "first visit" to your home and it is vital that the pictures leave them wanting to see more so they will then schedule a second "actual visit."
Buyers use on line photos as their first showing and decide which of many properties to see in person based on what they see on line. Sellers go online to see how agents they are considering listing with present their current listings before contacting them. The top agents who actually sell most properties generally realize this and use professional photographers. Most other agents don't have the skill or equipment to take consistently good photos, but will convince themselves what they produce is "good enough". I realized how important photos would be to marketing real estate in the internet age a number of years ago and invested in the equipment and training to become a professional real estate and architectural photographer both for my listings and for other agents, builders, etc. It makes a huge difference.
Making your agent aware of your displeasure with the photos would go a long way in getting the problem corrected....
I take.30.to 40the photos for my listings. Them go through those.photos.with.the.homes.owner and.pick the best ones.
Now hopefuly the photos were not taken with cell phone or tablet.
IMO.only a high resolution camera will do.
