SalesForce best way to store Images (issue with SF Storage space)

Hello Guys,
I need some help from your side and how to approve the following issue. One of the customer is using CRM solution integrated with SalesForce, so they are using Identity data (KYC) for registering Customer. All those information are stored in SF but the big issue is storing the (Profile) Images int SF which cause heavy consumption of storage space. So the question here is how to solve such issue? So what is the best option, to store images on some share and then access it there to show profile pictures or any other suggestions.
Thanks.
