The easiest option is to use the built in iCloud sync feature. Your appleID gives you 5GB of iCloud storage. In settings turn it on and make sure photo stream is on. This auto synchs any photos in your photo roll from last 30 days. Install the iCloud app on your mac or pc and it's all automatically sync'd to every device every time you take a photo or get wireless access.
