If you use iCloud, set it up on your PC and transfer the images that way. It’s also possible to use a browser on your computer, login to iCloud, and download the images from there.
If you use Dropbox or another cloud service, pictures can be synced to your computer.
There are a few USB flash drives for iDevices that can plug into the iPad (lightning port), to import images, and have a second connector for the computer. I’m using one of these, and it works quite well.
