I have iPad 3G (64g) and Photobucket Pro account as well as Flickr free account. I would like to take photos on my DSLR (Sony) and upload, organize, and view them online from my iPad (I don’t need to share the photos with others). I have been using Photobucket Pro account so far; however, I wonder if it is the best I can do on my iPad especially in terms of speed of browsing through the photos online (it is very slow). Could someone please tell me if I should stick with Photobucket Pro or switch to Flickr pro account by upgrading my free account to Pro?

All I can say is give it a try and make your choice based on your own needs. I don't use flickr so I can only say PB is enough for me. You're looking for something better so I'd say try it.

I havent played with Flickr much, but from what I can tell, photobucket makes it much easier to share you photos (and other people's photos) on the internet. Flickr is more protective of the actual image location, which professional photographers like.

I really like Photobucket, good luck with your choice.
