Accessing photos streamed to cloud

My friend's brother takes photos with his camera and downloads to his IPad to do slide shows of his medical charity work in Haiti. He does not have another computer. Is there a way to stream each year's slide show to the cloud and then access it again by collection or slideshow?

Dropbox

SmugMug and uSmugmug

Flickr

All sorts of ways he can put pictures in the cloud.

Thanks! DropBox is the perfect solution and it's easy enough for him to understand!

If he already has it, may want to also look at iPhoto for iOS' ability to do this (and post it online, though I don't think they've quite jelled it just yet).
