You can use iTunes or iCloud Photo Library to get them to your iPad. Just save the images and videos to the computer, then sync them to your iDevice via iTunes, or, if iCloud is installed on your computer, use it to get your content to the iPad.
If they are saved to Google Photos or Google Drive, install the app on your iPad. You can access and download your images from there as well. Online storage in general (OneDrive, Flickr, Box, ...) has apps that can show your photos and videos, as well as load them to your Photos app on the iPad.
