Can You Send Images to a Landline Number?

In short, not really. To get that kind of functionality would require a hefty investment in a virtual phone system, plus the ongoing costs might not be worth it.

At our workplace, we use Kenect, which enables us to send and receive texts from our work number including images. This setup might be a great fit for you.

For something like this to work, your phone provider would need to offer an SMS/MMS to email service. I don’t know of any that do, but it might be worth checking out. A VoIP line may suit your needs better since many providers allow customization options.

You could consider using fax technology. Customers would need to utilize an online fax service, and you'd need a fax machine as well. However, if you’d rather not go old school, think about switching to a VoIP service like Ring Central or Zoom Phone that offers SMS capabilities. Unfortunately, regular SMS can only handle text, not images, so it might just complicate things for your customers. The simplest solution might be to have them send images via email. If you want to upgrade further, developing a custom app for uploads would be an option, but that's quite an investment.

You can switch your landline to a service like Google Voice. Just keep in mind, it would turn your landline into more of a regular phone number than an actual landline.
