Unless you uploaded them to somewhere, or 'maybe' connected them to "Google Photos", without a power source, there really is no way to view/access them. Batteries can usually be gotten rather cheaply though. You can usually find them on say Amazon for less than $10, including shipping.
If you do have a google account attached to your phone, try logging into it from a computer and go to the Google Photos area. You "might" find them there. If not, then the only option is the replacement battery.
