Hello,
We just released Photo Transfer, an universal app (iPhone/iPadd) that lets you transfer multiple photos (up to 50 at one time) from your iPad to your Computer over wifi. You can also transfer photos from an iPhone or computer directly to your iPad. No cables and no other software required.
The app is currently in the top 25 iPad apps in the photography category. I hope you can check it out and find it useful:
