Depending on what you want to transfer to there are a number of good options. The easiest would be to connect your iPad to a Mac or PC through a USB cable that came with it and export/move photos that way. You can also sync your iPad photos to iCloud, and use the iCloud account on the other device you want to view the pictures from. this way your pictures are in the cloud and there's no need to transfer them. Another good option is using services such as dropbox that you can transfer the pictures through.
