Well, unfortunately you can't really recover your photos. If they were on a SD card it would be a lot more easier but it seems like the photos are in the internal storage.
There is still 1 thing you can try:
Your recovery! Find a way to boot your phone into the recovery. I assume your phone is still startable (not bootable). In most recoveries is an option for browsing the storage. If that's the case you just need to copy your photos to an external storage.
But what if your recovery doesn't support such a feature? But you must have tried the first option first because this option is more risky:
Download TWRP (twrp.me) <- You will love that thing ;D (EDIT: This will only work if your bootloader is unlocked!!!)
Copy the TWRP zip to your external storage
Boot in your recovery and flash the zip
Reboot into your recovery (should be TWRP now) and now I believe there is a way to open the doors to your internal storage for your computer. Otherwise there is an option for browsing your phones internal storage (on the phone)
Last step! Copy the whole thing over there ;D
Hope I helped ya! ;D
