If you are a local business, do include the area name if it makes sense to the users.

Image size should not be too big as it may slow down the page loading speed. Page speed is one of SEO ranking raking factors and their importance is even more in the age of smartphone and mobile internet. On the other hand image quality is important for user experience. So it is always recommended to go for a mix of image quality and size to find the balance between two.
