Connecting phone to laptop?

Hello,
I have an LGL39C. today I dropped it in the toilet while getting ready for work. I had it in a bag a rice which did help a little, I can hear the notifications going off but there is no screen. my phone company said they'll send a replacement but I cant get any of my pictures off the phone. I have the SD card but there were a couple hundred pictures on the phone itself. I tried using the usb cord like I usually do to transfer pics but it says the drivers are not installed. I've never had a problem with that before. it recognized the phone until the person from the phone company was looking at my account and then suddenly it wouldn't work, I assume that's the reason? is there anything I can download to try and get my pictures off the phone? im not a tech expert or anything, but any help is greatly appreciated
