Wi-Fi Photo Transfer is a free app that makes it insanely simple to download photos from your iPhone, iPod Touch, or iPad. This app is available on Apps store.The best part is that you dont need to have a jailbroken device.
There isn’t a single setting to alter once you download the app. It works by making the photos folder on your device (DCIM, if you’re an iOS explorer) visible from your web browser so you can download photos straight to your computer. Your computer and device must be on the same Wi-Fi network for this to work.
You can view all your photos in a convenient thumbnail view to select multiple items, or you can download them one by one (in various sizes, too).
Download it Free from App store.
