There is no way to upload photo directly to Facebook without a third party app. Hopefully in the future, Apple would integrate an upload to social networks like on BlackBerry or Android directly after a snapshot is taken. There are a few ways to upload your photos or videos to Facebook. There are the free way, then there are the pay way. First, there are limits to video size, which is 764Mb or 20 Minutes long. But as far as photos goes, that all depends if your iPad or iPhone has enough caching memory to upload lots of pictures all at once. About 1000 at a time works great, just depends on how fast is your upload speed of your Wi-Fi. But it seems like uploading anything more than 1000 to anywhere including WiFi Transfer to your PC or Mac will always fail.
I always get the question, how do you upload photos to Facebook? There are different apps for Facebook on the iPad, especially since Facebook don’t have an official Facebook app; there are 3rd party apps that will suffice for uploading your funny photos, or even your serious photos. Until Facebook comes with an official app for the iPad, you can check out the apps I tried that can upload photos to Facebook.
The most common app I use to upload my photos or videos is a paid app called Facely HD at http://itunes.apple.com/us/app/facely-for-facebook-hd-chat/id392550386?mt=8 (iTunes Link) for the iPad, and I use it for my iPad 2. I take pictures and videos with my iPad 2, and then I upload them with Facely HD. You can try the Facely HD for free or the pay version $0.99. Facely HD is a Universal App, which means it works for the iPhone, iPod Touch and iPad. I have the free version, and it works great for me. But you can only do one video or photo at a time, one or the other.
Web Albums at http://itunes.apple.com/us/app/web-albums-for-ipad-a-picasa/id364824944?mt=8 (iTunes Link) is another app, an app for Picasa and Facebook, the two that I mostly use, but you can also upload Videos and Photos with Web Albums directly to Facebook. I use Web Albums the most for uploading videos to Facebook, however, for photos, I use Facely HD. The reason I use Web Albums for Videos is that when the upload fails, Web Albums retain the information where it left off so I don’t have to start over. So if the upload is at 50%, it would continue uploading. It does the same for pictures, but I only use Web Albums to upload more than 10 pictures at a time.
There is also another app called Facebook App for iPhone which works on the iPad, but it won’t be in its Native Resolution. The only good thing about Facebook app for the iPhone is that it’s Free. No need to buy the app and it works straight to the point, even with videos. However, you can only upload one picture at a time, not like Web Albums.
To conclude, Web Albums can upload multiple photos at once, as long as it’s 1000 photos or less. It can upload videos as well. Web Albums can also upload multiple videos at once, and if the app crash when your iPad runs out of memory, it will resume the download, even when you are disconnected from Wi-Fi or 3G Dead Spot. I preferred Web Albums because it is the most versatile and I can upload more than one photos or videos at once rather than one at a time.
Update: October 10th, 2011
Facebook has updated their iOS App Universal for both the iPad and iPhone. So if you already have the iPhone version of Facebook App at http://itunes.apple.com/us/app/facebook/id284882215?mt=8 (iTunes Link), you can now download for iPad 2.
