Generally, the theme relevance and effect of paid websites are much better than those of free websites. For example, iStockPhoto, GettyImage and 123rf. As I mentioned above, you will be able to find very specific pictures related to your business. Be sure to check the authorization information of the photos on paid websites, that is, where they can only be used. If you use them in two places, it may involve infringement.

You can also use a variety of criteria to refine your search. Do you want people? Do you want illustrations? Do you want horizontal or vertical?
If you find a photo whose style you really like, but dating data whose subject isn't quite right, click on the photographer's username. You'll be taken to the photographer's portfolio, where you can explore their other work. You may find a photo that fits your needs, as photographers tend to shoot the same subject multiple times. (But remember, you still need to obtain copyright for the photo.
