I can't tell you how many times I have been at work and wanted to get a photo I had saved on my iMac at home. How I have handled it until now is through LogMein. I love the app and how it lets me access my desktop from away, but here is a free option that will let you scoop photos from your desktop/laptop iPhoto library and put them right onto your iPad. The app is called Cinq. The app is free and all you need to do is register with them, download a free app to your desktop/laptop and be on wifi. What happens then is almost magical. Simply open the Cinq app on your iPad, log into your account and before you can say holy toledo, you will be looking at your iPhoto library.
