Google announced a significant update to how they enable business owners to manage the photos of their business within their Google+ Business Profiles.
Google said:
Starting today, you can tell us which image you’d like to appear when customers search for your business on Google. Just log in to Google My Business on the web or in the Android or iOS apps, and visit the Photos section. While you’re there, you can also give your business a fresh look online by updating your profile, logo and cover photos.
To do so, go to Google My Business on the web or in the Android or iOS apps and click on manage your profile. Then click on the photos button and you will be able to manage an array of photos including identity photos, interior photos, exterior photos, photos at work, team photos and additional photos.
Here is a screen shot:
Here are the photo requirements:
- Format: JPG, PNG, TIFF, BMP
- Size: Between 10KB and 5MB
- Minimum resolution: 250px on the longest side for profile & logo photos; 720px on the longest side for other business photos
- Aspect ratio: The longer dimension of the photo should be no more than four times the shorter dimension. Landscape photos look better than portrait photos on Google products. Panoramic photos may use different aspect ratios.
- Quality: The photo should be in focus, well-lit, have no photoshop alterations, and no excessive use of filters. The image should represent reality.
There are actually a ton of business photo categories, which you can see here and more help on this over here.
