Yes, you can sync content via iTunes on your PC - if you don't have iTunes installed then you can download it from here : http://www.apple.com/itunes/download/
If you haven't synced the iPad to that computer before then you might find this page useful : https://discussions.apple.com/docs/DOC-3141
To sync photos via iTunes, connect your iPad to your PC and select it on the left-hand sidebar of your PC's iTunes (you can enable the sidebar via control-S if it doesn't show), and the use the Photos tab on the right-hand side of the iTunes screen to select and sync your photos to your iPad's Photos app. You will need to sync all the photos that you want on the iPad together in one go as only the most recent photo sync remains on the iPad - synced photos can't be deleted directly on the iPad, instead they are deleted by not including them in the next photo sync.
